This paper presents a study of the dynamical mechanisms behind the extraction of Jupiter-Saturn planetesimals into detached orbits belonging to the Oort Cloud or the sednoid population. In an embedded cluster, these are the global cluster tide and gravitational impulses acquired due to stellar encounters. Our study builds on a large set of numerical simulations of Oort Cloud and sednoid formation, whose statistical results are reported in an accompanying paper. The material is extensive, amounting to detailed data on the orbital evolutions of 288 000 planetesimals. We have developed two graphical tools for our work: (1) diagrams showing the extraction history of sednoids and Oort Cloud comets for each of 72 solar template stars; and (2) time profiles of the evolution of semi-major axis and perihelion distance for individual planetesimals. These help us identify the main triggers behind individual extractions due to intrinsic differences between the tidal and stellar flyby triggering mechanisms. The time scale of an encounter-based extraction never exceeds the duration of the encounter, while the tide operates on two time scales - the orbital periods of the planetesimal around the star and the star around the cluster centre. These periods are very different for sednoids but often similar for Oort Cloud comets. We note the absence of evidence for synergy between the tide and the encounters or between subsequent encounters, likely due to the fact that each effect depends strongly on the geometrical circumstances, and those are rarely repeatable. The balance between tide and encounters as dominating trigger varies between different cluster types. For clusters which are strongly concentrated with the primordial gas remaining for a few Myr, we discover a previously unnoticed phenomenon, which we call tidal purging. In this case, nearly all Oort Cloud comets with semi-major axes exceeding 7 000 astronomical units are ejected from the solar system on hyperbolic orbits due to the non-conservative nature of the cluster tide. In a separate study of the end states reached by all planetesimals, we find that an overwhelming majority undergo hyperbolic ejections, remain in orbits similar to the initial ones, or get physically removed from the solar system due to collisions with a planet or the Sun. | 9 |

Observed scaling relations in galaxies between baryons and dark matter global properties are key to shed light on the process of galaxy formation and on the nature of dark matter. Here, we study the scaling relation between the neutral hydrogen (H I) and dark matter mass in isolated rotationally supported disk galaxies at low redshift. We first show that state-of-the-art galaxy formation simulations predict that the H I-to-dark-halo mass ratio decreases with stellar mass for the most massive disk galaxies. We then infer dark matter halo masses from high-quality rotation curve data for isolated disk galaxies in the local Universe and report on the actual universality of the H I-to-dark halo mass ratio for these observed galaxies. This scaling relation holds for disks spanning a range of 4 orders of magnitude in stellar mass and 3 orders of magnitude in surface brightness. Accounting for the diversity of rotation curve shapes in our observational fits decreases the scatter of the H I-to-dark halo mass ratio while keeping it constant. This finding extends the previously reported discrepancy for the stellar-to-halo mass relation of massive disk galaxies within galaxy formation simulations to the realm of neutral atomic gas. Our result reveals that isolated galaxies with regularly rotating extended H I disks are surprisingly self-similar up to high masses, which hints at mass-independent self-regulation mechanisms that have yet to be fully understood. | 9 |

A well known property of the γ-ray sources detected by Cos-B in the 1970s, by the Compton Gamma-Ray Observatory in the 1990s, and recently by the Fermi observations is the presence of radio counterparts, particularly for those associated with extragalactic objects. This observational evidence is the basis of the radio-γ-ray connection established for the class of active galactic nuclei known as blazars. In particular, the main spectral property of the radio counterparts associated with γ-ray blazars is that they show a flat spectrum in the GHz frequency range. Our recent analysis dedicated to search blazar-like candidates as potential counterparts for the unidentified γ-ray sources allowed us to extend the radio-γ-ray connection in the MHz regime. We also showed that blazars below 1 GHz maintain flat radio spectra. Thus, on the basis of these new results, we assembled a low-frequency radio catalog of flat-spectrum sources built by combining the radio observations of the Westerbork Northern Sky Survey and of the Westerbork in the southern hemisphere catalog with those of the NRAO Very Large Array Sky survey (NVSS). This could be used in the future to search for new, unknown blazar-like counterparts of γ-ray sources. First, we found NVSS counterparts of Westerbork Synthesis Radio Telescope radio sources, and then we selected flat-spectrum radio sources according to a new spectral criterion, specifically defined for radio observations performed below 1 GHz. We also described the main properties of the catalog listing 28,358 radio sources and their logN-logS distributions. Finally, a comparison with the Green Bank 6 cm radio source catalog was performed to investigate the spectral shape of the low-frequency flat-spectrum radio sources at higher frequencies. | 9 |

Context. Modern graphics processing units (GPUs) lead to a major increase in the performance of the computation of astrophysical simulations. Owing to the different nature of GPU architecture compared to traditional central processing units (CPUs) such as x86 architecture, existing numerical codes cannot be easily migrated to run on GPU. Here, we present a new implementation of the numerical method smooth particle hydrodynamics (SPH) using CUDA and the first astrophysical application of the new code: the collision between Ceres-sized objects. <BR /> Aims: The new code allows for a tremendous increase in speed of astrophysical simulations with SPH and self-gravity at low costs for new hardware. <BR /> Methods: We have implemented the SPH equations to model gas, liquids and elastic, and plastic solid bodies and added a fragmentation model for brittle materials. Self-gravity may be optionally included in the simulations and is treated by the use of a Barnes-Hut tree. <BR /> Results: We find an impressive performance gain using NVIDIA consumer devices compared to our existing OpenMP code. The new code is freely available to the community upon request. <P />If you are interested in our CUDA SPH code miluphCUDA, please write an email to Christoph Schäfer. miluphCUDA is the CUDA port of miluph. miluph is pronounced [maßl2v]. We do not support the use of the code for military purposes. | 9 |

LWA1 is a new radio telescope operating in the frequency range 10-88 MHz, located in central New Mexico. The telescope consists of 258 pairs of dipole-type antennas whose outputs are individually digitized and formed into beams. Simultaneously, signals from all dipoles can be recorded using one of the instrument's "all dipoles" modes, facilitating all-sky imaging. Notable features of the instrument include high intrinsic sensitivity (about 6 kJy zenith system equivalent flux density), large instantaneous bandwidth (up to 78 MHz), and 4 independently-steerable beams utilizing digital "true time delay" beamforming.

We present two- and three-dimensional hydrodynamic simulations of ~kpc-scale AGN jets with mean jet powers in the range 1-7 × 10<SUP>45</SUP> erg s<SUP>-1</SUP>, in which the jet power varies (through variation of the Lorentz factor) according to a flicker or pink noise power spectrum. We find the morphology and dynamics of the jet-cocoon system depends on the amplitude of the variability with a clear correspondence between the shape of the cocoon and the historical activity. The jet advances quickly during high-power states, whereas quiescent periods instead produce passive periods of inflation resembling Sedov-Taylor blast waves. Periods of high activity preferentially produce hotspots and create stronger backflow as they maximize the pressure gradient between the jet head and cocoon. The variability can also lead to propagating internal shock structures along the jet. Our work suggests that variability and flickering in the jet power has important implications, which we discuss, for observations of radio galaxies, ultrahigh energy cosmic ray acceleration and jet power to luminosity correlations. We explore the link between morphology and fuelling, and suggest that chaotic cold accretion should introduce a relatively small scatter in radio luminosity (~0.2 dex) and modest imprints on morphology; sources such as Hercules A and Fornax A, which show evidence for more dramatic variability, may therefore require redder power spectra, or be triggered by mergers or other discrete events. We suggest ways to search for jet flickering observationally and propose that radio galaxies may be an important diagnostic of Myr time-scale AGN fuelling, due to their 'long-term memory'. | 9 |

Gamma-ray bursts (GRBs) have long been considered a possible source of high-energy neutrinos. While no correlations have yet been detected between high-energy neutrinos and GRBs, the recent observation of GRB 221009A-the brightest GRB observed by Fermi-GBM to date and the first one to be observed above an energy of 10 TeV-provides a unique opportunity to test for hadronic emission.

The most massive black holes at redshifts z = 6 were already over billion solar masses. In this chapter, we discuss the formation and growth of the first black holes in the Universe. The deaths of massive primordial stars provide potential seeds of supermassive black holes. Theoretical models predict that the seed black hole masses range from 10 to 100,000 solar masses. Their initial fueling may be limited by feedback from its progenitor star, the black hole itself, and nearby star formation. Once the halo and galaxy surpasses a critical mass, black hole growth may accelerate as the central gravitational potential deepens with strong ensuing star formation. | 9 |

The ultraviolet (UV)/optical variations in many active galactic nuclei are very well correlated, showing delays that increase with increasing wavelength. It is thought that this is due to thermal reprocessing of the X-ray emission by the accretion disk. In this scenario, the variable X-ray flux from the corona illuminates the accretion disk where it is partially reflected, and partially absorbed and thermalized in the disk producing a UV/optical reverberation signal. This leads to time lags that increase with wavelength. However, although the shape of the observed time lags as a function of wavelength is consistent with the model predictions, their amplitude suggests the presence of a disk that is significantly hotter than expected. In this work, we estimate the response functions and the corresponding time lags assuming a standard Novikov-Thorne accretion disk illuminated by a point-like X-ray source. We take into account all relativistic effects in the light propagation from the X-ray source to the disk then to the observer. We also compute the disk reflection, accounting for its ionization profile. Our results show that thermal reverberation effects are stronger in sources with large X-ray source height and low accretion rate. We also found that the time lags increase with height and accretion rate. We apply our model to NGC 5548 and show that the observed lags in this source can be explained by the model for a source height of ∼60 r <SUB>g</SUB> and an accretion rate of a few percent of the Eddington limit for a maximally spinning black hole. | 9 |

Accurate and fast gravitational waveform (GW) models are essential to extract information about the properties of compact binary systems that generate GWs. Building on previous work, we present an extension of the NRTidal model for binary neutron star (BNS) waveforms. The upgrades are (i) a new closed-form expression for the tidal contribution to the GW phase which includes further analytical knowledge and is calibrated to more accurate numerical relativity data than previously available; (ii) a tidal correction to the GW amplitude; and (iii) an extension of the spin-sector incorporating equation-of-state-dependent finite size effects at quadrupolar and octupolar order; these appear in the spin-spin tail terms and cubic-in-spin terms, both at 3.5 PN. We add the new description to the precessing binary black hole waveform model IMRPhenomPv2 to obtain a frequency-domain precessing binary neutron star model. In addition, we extend the SEOBNRv4_ROM and IMRPhenomD aligned-spin binary black hole waveform models with the improved tidal phase corrections. Focusing on the new IMRPhenomPv2_NRTidalv2 approximant, we test the model by comparing with numerical relativity waveforms as well as hybrid waveforms combining tidal effective-one-body and numerical relativity data. We also check consistency against a tidal effective-one-body model across large regions of the BNS parameter space. | 9 |

We present Atacama Large Millimeter/submillimeter Array (ALMA) imaging of molecular gas across the full star-forming disk of the barred spiral galaxy M83 in CO(J = 1-0). We jointly deconvolve the data from ALMA's 12 m, 7 m, and Total Power arrays using the MIRIAD package. The data have a mass sensitivity and resolution of 10<SUP>4</SUP> M <SUB>⊙</SUB> (3σ) and 40 pc-sufficient to detect and resolve a typical molecular cloud in the Milky Way with a mass and diameter of 4 × 10<SUP>5</SUP> M <SUB>⊙</SUB> and 40 pc, respectively. The full disk coverage shows that the characteristics of molecular gas change radially from the center to outer disk, with the locally measured brightness temperature, velocity dispersion, and integrated intensity (surface density) decreasing outward. The molecular gas distribution shows coherent large-scale structures in the inner part, including the central concentration, offset ridges along the bar, and prominent molecular spiral arms. However, while the arms are still present in the outer disk, they appear less spatially coherent, and even flocculent. Massive filamentary gas concentrations are abundant even in the interarm regions. Building up these structures in the interarm regions would require a very long time (≳100 Myr). Instead, they must have formed within stellar spiral arms and been released into the interarm regions. For such structures to survive through the dynamical processes, the lifetimes of these structures and their constituent molecules and molecular clouds must be long (≳100 Myr). These interarm structures host little or no star formation traced by Hα. The new map also shows extended CO emission, which likely represents an ensemble of unresolved molecular clouds. | 9 |

We present new stellar velocity dispersion measurements for four luminous quasars with the Near-Infrared Integral Field Spectrometer instrument and the ALTAIR laser guide star adaptive optics system on the Gemini North 8 m telescope. Stellar velocity dispersion measurements and measurements of the supermassive black hole (BH) masses in luminous quasars are necessary to investigate the coevolution of BHs and galaxies, trace the details of accretion, and probe the nature of feedback. We find that higher-luminosity quasars with higher-mass BHs are not offset with respect to the M <SUB>BH</SUB>-σ<SUB>*</SUB> relation exhibited by lower-luminosity active galactic nuclei (AGNs) with lower-mass BHs, nor do we see correlations with galaxy morphology. As part of this analysis, we have recalculated the virial products for the entire sample of reverberation-mapped AGNs and used these data to redetermine the mean virial factor langfrang that places the reverberation data on the quiescent M <SUB>BH</SUB>-σ<SUB>*</SUB> relation. With our updated measurements and new additions to the AGN sample, we obtain langfrang = 4.31 ± 1.05, which is slightly lower than, but consistent with, most previous determinations. | 9 |

We present a positive correlation between the mass of dense molecular gas ({M}<SUB>{{dense</SUB>}}) of ∼100 pc scale circumnuclear disks (CNDs) and the black hole mass accretion rate ({\dot{M}}<SUB>{{BH</SUB>}}) in a total of 10 Seyfert galaxies, based on data compiled from the literature and an archive (median aperture θ <SUB>med</SUB> = 220 pc). A typical {M}<SUB>{{dense</SUB>}} of CNDs is 10<SUP>7-8</SUP> {M}<SUB>⊙ </SUB>, estimated from the luminosity of the dense gas tracer, the HCN(1-0) emission line. Because dense molecular gas is the site of star formation, this correlation is virtually equivalent to the one between the nuclear star-formation rate and {\dot{M}}<SUB>{{BH</SUB>}} revealed previously. Moreover, the {M}<SUB>{{dense</SUB>}}{--}{\dot{M}}<SUB>{{BH</SUB>}} correlation was tighter for CND-scale gas than for the gas on kiloparsec or larger scales. This indicates that CNDs likely play an important role in fueling black holes, whereas greater than kiloparesec scale gas does not. To demonstrate a possible approach for studying the CND-scale accretion process with the Atacama Large Millimeter/submillimeter Array, we used a mass accretion model where angular momentum loss due to supernova explosions is vital. Based on the model prediction, we suggest that only the partial fraction of the mass accreted from the CND ({\dot{M}}<SUB>{{acc</SUB>}}) is consumed as {\dot{M}}<SUB>{{BH</SUB>}}. However, {\dot{M}}<SUB>{{acc</SUB>}} agrees well with the total nuclear mass flow rate (I.e., {\dot{M}}<SUB>{{BH</SUB>}} + outflow rate). Although these results are still tentative with large uncertainties, they support the view that star formation in CNDs can drive mass accretion onto supermassive black holes in Seyfert galaxies. | 9 |
