(and a first for me) in collaboration with Michele Mastropietro (@mic_mas), Sven De Rijcke, Carmen Gallart, Edouard Bernard and Robbert Verbeke (@Rbhfd): ""Observations"" of simulated dwarf galaxies (<LINK>). In this paper, we observationally analyze a set of realistically simulated MoRIA dwarf galaxies (from the work of @Rbhfd), to look for any systematic bias in comparison of simulations with observations. In particular, we use the synthetic color-magnidue diagram (CMD) technique to reconstruct the star formation history (SFH) of dwarf galaixes. We construct CMDs of simulated dwarfs from simulation star particle data and add observational errors to mimic real observations. On comparing the reconstructed SFH from the synthetic CMD method with the ground truth from the simulation star particle data, we overall find a good agreement. Our paper also explores: 1) the effect of dust extinction on the CMD, and hence on the reconstructed SFH, and 2) the dependence on the SFH on the aperture used. We also analyze infrared CMDs, in view of the next generation astronomical facilities.",https://arxiv.org/abs/2007.11413,"Apparent deviations between properties of dwarf galaxies from observations and simulations are known to exist, such as the ""Missing Dwarfs"" problem, the too-big-to-fail problem, and the cusp-core problem, to name a few. Recent studies have shown that these issues can at least be partially resolved by taking into account the systematic differences between simulations and observations. This work aims to investigate and address any systematic differences affecting the comparison of simulations with observations. To this aim, we analyzed a set of 24 realistically simulated MoRIA (Models of Realistic dwarfs In Action) dwarf galaxies in an observationally motivated way. We first constructed ""observed"" color-magnitude diagrams (CMDs) of the simulated dwarf galaxies in the typically used V- and I-bands. Then we used the CMD-fitting method to recover their star-formation histories (SFHs) from their observed CMDs. These solved SFHs were then directly compared to the true SFHs from the simulation star-particle data, mainly in terms of the star-formation rate(SFR) and the age-metallicity relation (AMR). We applied a dust extinction prescription to the simulation data to produce observed CMDs affected by dust in star-formation regions. Since future facilities, such as the JWST and E-ELT will focus on the near IR rather than the optical, we also constructed and analyzed CMDs using the I- and H-bands. We find a very good agreement between the recovered and the true SFHs of all the simulated dwarf galaxies in our sample, from the synthetic CMD analysis of their V-I versus I as well as the I-H versus H CMDs. Dust leads to an underestimation of the SFR during the last few hundred million years. Overall, our analysis indicates that quantities like SFR and AMR derived from the photometric observations of galaxies are directly comparable to their simulated counterparts.
