Context. The presence of [α/Fe]-[Fe/H] bi-modality in the Milky Way disc has intrigued the Galactic archaeology community over more than two decades. <BR /> Aims: Our goal is to investigate the chemical, temporal, and kinematical structure of the Galactic discs using abundances, kinematics, and ages derived self-consistently with the new Bayesian framework SAPP. <BR /> Methods: We employed the public Gaia-ESO spectra, as well as Gaia EDR3 astrometry and photometry. Stellar parameters and chemical abundances are determined for 13 426 stars using NLTE models of synthetic spectra. Ages were derived for a sub-sample of 2898 stars, including subgiants and main-sequence stars. The sample probes a large range of Galactocentric radii, ∼3 to 12 kpc, and extends out of the disc plane to ±2 kpc. <BR /> Results: Our new data confirm the known bi-modality in the [Fe/H]-[α/Fe] space, which is often viewed as the manifestation of the chemical thin and thick discs. The over-densities significantly overlap in metallicity, age, and kinematics and none of them offer a sufficient criterion for distinguishing between the two disc populations. In contrast to previous studies, we find that the α-poor disc population has a very extended [Fe/H] distribution and contains ∼20% old stars with ages of up to ∼11 Gyr. <BR /> Conclusions: Our results suggest that the Galactic thin disc was in place early, at lookback times corresponding to redshifts of z ∼ 2 or more. At ages of ∼9 to 11 Gyr, the two disc structures shared a period of co-evolution. Our data can be understood within the clumpy disc formation scenario that does not require a pre-existing thick disc to initiate the formation of the thin disc. We anticipate that a similar evolution can be realised in cosmological simulations of galaxy formation. <P />Full tables of T<SUB>eff</SUB>, log g, NLTE [Fe/H], [Mg/Fe], Vmic Ages, and uncertainties are available at the CDS via anonymous ftp to <A href="https://cdsarc.cds.unistra.fr">cdsarc.cds.unistra.fr</A> (ftp://130.79.128.5) or via <A href="https://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/683/A74">https://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/683/A74</A> <P />Based on observations made with the ESO/VLT, at Paranal Observatory, under program 188.B-3002 (The Gaia-ESO Public Spectroscopic Survey, PIs: G.

Using the Eight MIxer Receiver (EMIR) instrument on the Institut de RadioAstronomie Millimétrique (IRAM) 30-m telescope, we conducted a spectroscopic redshift search of seven z<SUB>phot</SUB> ∼ 4 submillimetre bright galaxies selected from the Herschel Bright Sources sample with fluxes at 500 μm greater than 80 mJy. For four sources, we obtained spectroscopic redshifts between 3.4 < z < 4.1 through the detection of multiple CO-spectral lines with J ≥ 3. Later, we detected low-J transitions for two of these sources with the Green Bank Telescope including the CO(1-0) transition. For the remaining three sources, more data are needed to determine the spectroscopic redshift unambiguously. The measured CO luminosities and line widths suggest that all these sources are gravitationally lensed. These observations demonstrate that the 2 mm window is indispensable to confirm robust spectroscopic redshifts for z < 4 sources. Finally, we present an efficient graphical method to correctly identify spectroscopic redshifts. | 9 |

We revisit the constraint on the maximum mass of cold spherical neutron stars coming from the observational results of GW170817. We develop a new framework for the analysis by employing both energy and angular momentum conservation laws as well as solid results of latest numerical-relativity simulations and of neutron stars in equilibrium. The new analysis shows that the maximum mass of cold spherical neutron stars can be only weakly constrained as M<SUB>max</SUB>≲2.3 M<SUB>⊙</SUB>. Our present result illustrates that the merger remnant neutron star at the onset of collapse to a black hole is not necessarily rapidly rotating and shows that we have to take into account the angular momentum conservation law to impose the constraint on the maximum mass of neutron stars. | 9 |

We investigate Wray 15-811, a poorly studied object of controversial nature. We present for the first time spectroscopic observations (at low, medium, and high resolution), together with deep narrow-band images. These original data are combined with data from public surveys, to infer the nature of this object. <P />We conclude that Wray 15-811 is indeed a carbon star with an optical bow-shock nebula associated. Its spectrum displays a split H α emission, and its SED indicates the presence of silicates features. The light curve is similar to the expected for a Mira variable with a 504-day period. Its proper motion is compatible with that of a runaway star, consistent with the presence of the observed bow-shock nebula. | 9 |
Binary stars including an AGB star hold the clues for understanding important phenomena in stellar evolution, such as common-envelope events, the formation of SN-Ia, and the origin of aspherical pPNe/PNe. Hydro-dynamical codes simulating the companion's influence on the primary mass loss exist, but we still lack information on the orbital parameters of systems where these models can be tested. The best case where this can be pursued is R Aqr. Here, we present the results of the first-ever determination of the whole set of orbital parameters of the system purely based on observational data. The results agree very well with the observational characteristics of the nebula around the system. Reasonable values for the stellar masses agree with distances from period- and diameter-luminosity relationships for Mira variables, but not with those from VLBI observations of SiO masers or GAIA. | 9 |

In order to investigate the relation between magnetic structures and the signatures of heating in plage regions, we observed a plage region with the He I 1083.0 nm and Si I 1082.7 nm lines on 2018 October 3 using the integral field unit mode of the GREGOR Infrared Spectrograph (GRIS) installed at the GREGOR telescope. During the GRIS observation, the Interface Region Imaging Spectrograph obtained spectra of the ultraviolet Mg II doublet emitted from the same region. In the periphery of the plage region, within the limited field of view seen by GRIS, we find that the Mg II radiative flux increases with the magnetic field in the chromosphere with a factor of proportionality of 2.38 × 10<SUP>4</SUP> erg cm<SUP>-2</SUP> s<SUP>-1</SUP> G<SUP>-1</SUP>. The positive correlation implies that magnetic flux tubes can be heated by Alfvén wave turbulence or by collisions between ions and neutral atoms relating to Alfvén waves. Within the plage region itself, the radiative flux was large between patches of strong magnetic field strength in the photosphere or at the edges of magnetic patches. On the other hand, we do not find any significant spatial correlation between the enhanced radiative flux and the chromospheric magnetic field strength or the electric current. In addition to the Alfvén wave turbulence or collisions between ions and neutral atoms relating to Alfvén waves, other heating mechanisms related to magnetic field perturbations produced by interactions of magnetic flux tubes could be at work in the plage chromosphere. | 9 |
Rowlinson et al. 2023 recently claimed the detection of a coherent radio flash 76.6 minutes after a short gamma-ray burst. They proposed that the radio emission may be associated with a long-lived neutron star engine. We show through theoretical and observational arguments that the coherent radio emission, if real and indeed associated with GRB 201006A and at the estimated redshift, is unlikely to be due to the collapse of the neutron star, ruling out a blitzar-like mechanism. Instead, we show if a long-lived engine was created, it must have been stable with the radio emission likely linked to the intrinsic magnetar activity. However, we find that the optical upper limits require fine-tuning to be consistent with a magnetar-driven kilonova: we show that neutron-star engines that do satisfy the optical constraints would have produced a bright kilonova afterglow that should already be observable by the VLA or MeerKAT (for ambient densities typical for short GRBs). Given the optical limits and the current lack of a kilonova afterglow, we instead posit that no neutron star survived the merger, and the coherent radio emission was produced far from a black hole central engine via mechanisms such as synchrotron maser or magnetic reconnection in the jet -- a scenario consistent with all observations. We encourage future radio follow-up to probe the engine of this exciting event and continued prompt radio follow-up of short GRBs. | 9 |

This paper highlights initial photometric analyses of JWST NIRCam imaging data in the sightline of SMACS0723, aiming to identify galaxies at redshift z > 7. By applying a conservative Lyman-break selection followed by photometric-redshift analysis and visual inspection, we identify four F090W-dropout and two F150W-dropout sources, three of which were recently confirmed in an independent spectroscopic analysis to z = 7.663, 7.665, and 8.499. We then supplement our sample with a photometric-redshift selection, and identify five additional candidates at 7 < z <SUB>phot</SUB> < 13. The NIRCam images clearly resolve all sources and reveal their subgalactic components that were not resolved/detected in the previous imaging by Hubble Space Telescope. Our spectral energy distribution analysis reveals that the selected galaxies are characterized by young stellar populations (median age of ~50 Myr) of subsolar metallicity (~0.2 Z <SUB>⊙</SUB>) and little dust attenuation (A <SUB> V </SUB> ~ 0.5). In several cases, we observe extreme Hβ+[O III] lines being captured in the F444W band and seen as color excess, which is consistent with their observed high star formation rate surface density. Eight of the 11 sources identified in this study appear in at least one of the recent studies (Adams et al.; Atek et al.; Donnan et al.; Harikane et al.; Yan et al.) of the same fields, implying the high fidelity of our selection. We crossmatch all high-z galaxy candidates presented in the five studies with our catalog and discuss the possible causes of discrepancy in the final lists. | 9 |

Recently born magnetars are promising candidates for the engines powering fast radio bursts (FRBs). The focus thus far has been placed on millisecond magnetars born in rare core-collapse explosions, motivated by the star-forming dwarf host galaxy of the repeating FRB 121102, which is remarkably similar to the hosts of superluminous supernovae and long gamma-ray bursts. However, long-lived magnetars may also be created in binary neutron star (BNS) mergers, in the small subset of cases with a sufficiently low total mass for the remnant to avoid collapse to a black hole, or in the accretion-induced collapse (AIC) of a white dwarf. A BNS or AIC FRB channel will be characterized by distinct host galaxy and spatial offset distributions which we show are consistent with the recently reported FRB 180924, localized by the Australian Square Kilometre Array Pathfinder to a massive quiescent host galaxy with an offset of about 1.4 effective radii. Using models calibrated to FRB 121102, we make predictions for the dispersion measure, rotation measure, and persistent radio emission from magnetar FRB sources born in BNS mergers or AIC, and show these are consistent with upper limits from FRB 180924. Depending on the rate of AIC, and the fraction of BNS mergers leaving long-lived stable magnetars, the birth rate of repeating FRB sources associated with older stellar populations could be comparable to that of the core-collapse channel. We also discuss potential differences in the repetition properties of these channels, as a result of differences in the characteristic masses and magnetic fields of the magnetars. | 9 |

The main feature of this release is the overhauling of how the framework computes the gradients of observables with respect to force field parameters. In particular, from this release onwards all gradients will be computed using the fluctuation formula (also referred to as the thermodynamic gradient), rather than calculation be the re-weighted finite difference approach (PR #280). In general the two methods produce gradients which are numerically indistinguishable, and so this should not markedly change any scientific output of this framework. The change was made to, in future, enable better integration with automatic differentiation libraries such as jax, and differentiable simulation engines such as timemachine which readily and rapidly give access to dU/dθ. Additionally, as of version 0.3.0 \'known\' charges (i.e. those assigned to TIP3P water and ions) are no longer automatically applied when using a SMIRNOFF based force field. This feature was originally included in the framework as the OpenFF toolkit did not support defining charges on specific molecules in the force field itself. This is now fully supported through the LibraryCharges section of a SMIRNOFF force field and hence this workaround is no longer required. From now on all ion and water charges must be specified in the SMIRNOFF force field. Finally, this release includes beta support for computing host-guest binding affinities using the attach-pull-release (APR) method through integration with the pAPRika and taproom packages. This support was largely facilitated by the efforts of the paprika authors - David R. Slochower and Jeffry Setiadi. Bugfixes PR #285: Use merged protocols in workflow provenance.

We present ethraid, an open-source Python package designed to measure the mass (m <SUB> c </SUB>) and separation (a) of a bound companion from measurements covering a fraction of the orbital period. ethraid constrains m <SUB> c </SUB> and a by jointly modeling radial velocity, astrometric, and/or direct imaging data in a Bayesian framework. Partial orbit data sets, especially those with highly limited phase coverage, are represented well by a few method-specific summary statistics. By modeling these statistics rather than the original data, ethraid optimizes computational efficiency with minimal reduction in accuracy. ethraid uses importance sampling to efficiently explore the often broad posteriors that arise from partial orbits. The core computations of ethraid are implemented in Cython for speed. We validate ethraid's performance by using it to constrain the masses and separations of the planetary companions to HD 117207 and TOI-1694. We designed ethraid to be both fast and simple, as well as to give broad, "quick look" constraints on companion parameters using minimal data. ethraid is pip installable and available on Zenodo and GitHub. | 9 |
We examine the wavelength dependence of radial light profiles based on Sérsic index n measurements of 1067 galaxies with M <SUB>*</SUB> ≥ 10<SUP>9.5</SUP> M <SUB>⊙</SUB> and in the redshift range 0.5 < z < 3. The sample and rest-frame optical light profiles are drawn from the Cosmic Assembly Near-infrared Deep Extragalactic Legacy Survey (CANDELS) and 3D Hubble Space Telescope (HST); rest-frame near-infrared light profiles are inferred from images collected for the Cosmic Evolution Early Release Science (CEERS) program with the Near Infrared Camera (NIRCam) on board of the James Webb Space Telescope (JWST). n shows only a weak dependence on the wavelength, regardless of the redshift, galaxy mass, and type. On average, star-forming galaxies have n = 1-1.5 and quiescent galaxies have n = 3-4 in the rest-frame optical and near-infrared. The strong correlation at all wavelengths between n and star formation activity implies a physical connection between the radial stellar mass profile and star formation activity. The main caveat is that the current sample is too small to discern trends for the most massive galaxies (M <SUB>*</SUB> > 10<SUP>11</SUP> M <SUB>⊙</SUB>). | 9 |
Recently, a new class of white dwarfs ("slowly cooling WDs") has been identified in the globular cluster M13. The cooling time of these stars is increased by stable thermonuclear hydrogen burning in their residual envelope. These WDs are thought to be originated by horizontal branch (HB) stars populating the HB blue tail that skipped the asymptotic giant branch phase. To further explore this phenomenon, we took advantage of deep photometric data acquired with the Hubble Space Telescope in the near-ultraviolet and investigate the bright portion of the WD cooling sequence in NGC 6752, another Galactic globular cluster with a metallicity, age, and HB morphology similar to M13. The normalized WD luminosity function derived in NGC 6752 turns out to be impressively similar to that observed in M13, in agreement with the fact that the stellar mass distribution along the HB of these two systems is almost identical. As in the case of M13, the comparison with theoretical predictions is consistent with ~70% of the investigated WDs evolving at slower rates than standard, purely cooling WDs. Thanks to its relatively short distance from Earth, NGC 6752 photometry reaches a luminosity 1 order of a magnitude fainter than the case of M13, allowing us to sample a regime where the cooling time delay, with respect to standard WD models, reaches ~300 Myr. The results presented in this paper provide new evidence for the existence of slowly cooling WDs and further support to the scenario proposing a direct causal connection between this phenomenon and the HB morphology of the host stellar cluster. | 9 |

Incoherent solar radio radiation comes from the free-free, gyroresonance, and gyrosynchrotron emission mechanisms. Free-free is primarily produced from Coulomb collisions between thermal electrons and ions. Gyroresonance and gyrosynchrotron result from the acceleration of low-energy electrons and mildly relativistic electrons, respectively, in the presence of a magnetic field. In the non-flaring Sun, free-free is the dominant emission mechanism with the exception of regions of strong magnetic fields which emit gyroresonance at microwaves. Due to its ubiquitous presence, free-free emission can be used to probe the non-flaring solar atmosphere above temperature minimum. Gyroresonance opacity depends strongly on the magnetic field strength and orientation; hence it provides a unique tool for the estimation of coronal magnetic fields. Gyrosynchrotron is the primary emission mechanism in flares at frequencies higher than 1-2 GHz and depends on the properties of both the magnetic field and the accelerated electrons, as well as the properties of the ambient plasma. In this paper we discuss in detail the above mechanisms and their diagnostic potential. | 9 |
Context. Among the different observational techniques used to select high-redshift galaxies, the hydrogen recombination line Lyman-alpha (Lyα) is of particular interest because it gives access to the measurement of cosmological quantities such as the star formation rate (SFR) of distant galaxy populations. However, interpreting this line and calibrating such observables are still subject to serious uncertainties. <BR /> Aims: In this context, it important to understand the mechanisms responsible for the attenuation of Lyα emission, and under what conditions the Lyα emission line can be used as a reliable star formation diagnostic tool. <BR /> Methods: We used a sample of 24 Lyα emitters at z ~ 0.3 with an optical spectroscopic follow-up to calculate the Lyα escape fraction and its dependence upon different physical properties. We also examined the reliability of Lyα as a SFR indicator. We combined these observations with a compilation of Lyα emitters selected at z = 0-0.3 from the literature to assemble a larger sample. <BR /> Results: We confirm that the Lyα escape fraction clearly depends on the dust extinction following the relation f<SUB>esc</SUB>(Lyα) = C<SUB>Lyα</SUB> × 10<SUP>-0.4 E(B-V) k<SUB>Lyα</SUB></SUP> where k<SUB>Lyα</SUB> ~ 6.67 and C<SUB>Lyα</SUB> = 0.22. However, the correlation does not follow the expected curve for a simple dust attenuation. A higher attenuation can be attributed to a scattering process, while f<SUB>esc</SUB>(Lyα) values that are clearly above the continuum extinction curve can be the result of various mechanisms that can lead to an enhancement of the Lyα output. We also observe that the strength of Lyα and the escape fraction appear unrelated to the galaxy metallicity. Regarding the reliability of Lyα as a SFR indicator, we show that the deviation of SFR(Lyα) from the true SFR (as traced by the UV continuum) is a function of the observed SFR(UV), which can be seen as the decrease in f<SUB>esc</SUB>(Lyα) with increasing UV luminosity. Moreover, we observe redshift dependence of this relationship, revealing the underlying evolution of f<SUB>esc</SUB>(Lyα) with redshift. <P />Figure 13 and Tables 1 and 2 are available in electronic form at <A href="http://www.aanda.org/10.1051/0004-6361/201321519/olm">http://www.aanda.org</A>Reduced spectra are only available at the CDS via anonymous ftp to <A href="http://cdsarc.u-strasbg.fr">http://cdsarc.u-strasbg.fr</A> (ftp://130.79.128.5) or via <A href="http://cdsarc.u-strasbg.fr/viz-bin/qcat?J/A+A/561/A89">http://cdsarc.u-strasbg.fr/viz-bin/qcat?J/A+A/561/A89</A> | 9 |

Motivated by observational and theoretical work that suggest very small-scale (≲ 1 pc) structure in the circumgalactic medium of galaxies and in other environments, we study Lyman-α (Lyα) radiative transfer in an extremely clumpy medium with many clouds of neutral gas along the line of sight. While previous studies have typically considered radiative transfer through sightlines intercepting ≲ 10 clumps, we explored the limit of a very large number of clumps per sightline (up to f<SUB>c</SUB> 1000). Our main finding is that, for covering factors greater than some critical threshold, a multiphase medium behaves similarly to a homogeneous medium in terms of the emergent Lyα spectrum. The value of this threshold depends on both the clump column density and the movement of the clumps. We estimated this threshold analytically and compare our findings to radiative transfer simulations with a range of covering factors, clump column densities, radii, and motions. Our results suggest that (I) the success in fitting observed Lyα spectra using homogeneous "shell models" (and the corresponding failure of multiphase models) hints at the presence of very small-scale structure in neutral gas, which is in agreement within a number of other observations; and (II) the recurrent problems of reproducing realistic line profiles from hydrodynamical simulations may be due to their inability to resolve small-scale structure, which causes simulations to underestimate the effective covering factor of neutral gas clouds. <P />The movie associated to Fig. B.2 is available at <A href="http://www.aanda.org/10.1051/0004-6361/201731013/olm">http://www.aanda.org</A> | 9 |

One of the XRISM mission goals is to measure the gas dynamics of galaxy clusters with Resolve spectroscopy. To archive these, we propose an observation of the X-ray bright galaxy cluster Abell 2256 at z=0.06. This hosts 2nd brightest diffuse radio relic. Suzaku revealed a gas bulk motion at 1500 km/s, for the first time i\ n a cluster. This X-ray gas velocity is consistent with those measured in galaxy velocities, indicating that gas and galaxies are moving together. These and other observations make this system the most suitable for the XRISM spectral mapping of gas bulk and tur\ bulent motions and related physics. We propose two pointings to cover the central ~400kpc region. | 9 |
methods are provided for maximizing the throughput of a computer system in the presence of one or more power constraints . throughput is maximized by repeatedly or continuously or periodically optimizing task scheduling and assignment for each of a plurality of components of a computer system . the components include a plurality of central processing units each operating at a corresponding operating frequency . the components also include a plurality of disk drives . the corresponding operating frequencies of one or more cpus of the plurality of cpus are adjusted to maximize computer system throughput under one or more power constraints . optimizing task scheduling and assignment , as well as adjusting the corresponding operating frequencies of one or more cpus , are performed by solving a mathematical optimization problem using a first methodology over a first time interval and a second methodology over a second time interval longer than the first time interval . the first methodology comprises a short term heuristic solver for adapting to computer system changes that occur on a short time scale , and the second methodology comprises a long term solver having greater accuracy and greater computational complexity than the first methodology . | 8 |
an inclination adjustment fitting for seat backs of vehicle seats includes two fitting parts that are connected in a swiveling manner relative to each other via a wobble mechanism driven by an eccentric . the eccentric is formed from an eccentric ring and two wedge segments that are arranged in mirror image and set apart from each other and that in regions cover the circumference of the eccentric ring . the wedge segments are pressed apart by a spring acting against their one end faces for increasing the eccentricity and which are capable of being acted upon against the force of the spring by driving elements between the other end faces . the spring is supported on the eccentric such that the wedge segments occupy a defined position relative to the eccentric ring . | 1 |
in an internal combustion engine a fuel - air mixture having compression temperatures and pressures sufficiently low as not to support auto ignition , ignition is achieved by injecting igniting active radicals into the air - fuel mixture . in one embodiment the active radicals are provided by withdrawing a portion of the mixture , treating it to produce active radicals in the portion and returning the portion to the mixture . treatment of the portion typically includes simultaneously injecting , mixing , and compression of a predetermined amount of pilot fuel within the portion . | 5 |
