New hydrodynamical simulations show that dwarf galaxy stellar mass-halo mass relations and star formation histories are more influenced by host halo concentration than by the 5 cMpc scale environment.
FIRE-3 cosmological simulations of Seyfert galaxies produce episodic AGN feedback and gas clearing but no clear anti-correlation between nuclear gas concentration and AGN luminosity, highlighting timing mismatches with observations.
Photometric analysis yields metallicity distributions for 3917 stars across 12 faint Milky Way satellites, showing average [Fe/H] ~ -2.3 dex, 170 EMP candidates, and no gradients in ultra-faint systems.
Simulations demonstrate that high-specific-energy supernova outflows sustain hot CGM at virial temperature, raise t_cool/t_ff above 10, and transition dwarf galaxy feedback from ejective to preventive mode around 5 Gyr.
FOGGIE cosmological simulations find that less HI-populated CGMs produce thin, coherently rotating extended disks while more populated CGMs yield irregular morphologies, with all systems settling kinematically by z=0 independent of mass.
Interstellar objects may contribute enough baryonic mass to reduce the local dark matter halo density to 0.24 GeV/cm³.
Simulations indicate LISA could statistically distinguish CDM from SIDM (constant 1 cm²/g cross-section) with at least ~70 high-SNR massive black hole merger detections.
GREX-PLUS is a proposed JAXA L-class mission with a 1m cooled telescope, wide-field 2-8um camera, and R=30000 spectrometer in 10-18um to enable studies of z>15 galaxies, protoplanetary snowlines, and related astrophysics.
