Metallicity-dependent explodability prescriptions for massive stars reproduce observed galactic abundance trends when used in chemical evolution models and permit a simplified form that alleviates the red supergiant problem without violating those trends, provided net outflows are negligible and the

New CCSN yield tables at varying metallicities are inserted into galactic chemical evolution models and tuned to reproduce the Si-group and Fe-group abundances measured by Hitomi in the Perseus Cluster.
Revised solar photospheric abundances yield Z/X = 0.0187 with C, N, O at 8.46, 7.83, 8.69, preserving the solar modeling discrepancy and revealing a modest volatile-refractory offset from CI chondrites.
The PFS Galactic Archaeology survey will observe thousands of stars in Local Group systems to measure density profiles in dwarfs and compare assembly histories of M31 and the Milky Way.
The OBSIDIAN simulation with its three-regime AGN feedback best reproduces the observed stellar masses, star formation rates, and ages of brightest group galaxies, unlike the other simulations which show mismatches in quenching behavior.
