Recent cosmological hydrodynamical simulations have produced populations of numerical galaxies whose global star-forming properties are in good agreement with those observed galaxies. Proper modeling energetic feedback from supernovae and active galactic nuclei is critical to the ability reproduce galaxy and, historically, such modelling has proven be a challenge. Here, we analyze local central satellite $z=0$ snapshot TNG100 simulation as test models. We generate face-on projection stellar particles galaxies, which demonstrate existence resolved main sequence ($Σ_{SFR}$--$Σ_*$ relation) slope normalization that reasonable previous studies. also present radial profiles various for two parameters: distance line ($ΔΣ_{SFR}$) luminosity-weighted age ($age_L$). find that, on average, high-mass quench inside-out, while low-mass similar, flatter profiles.
