Stellar streams encode the initial mass function of globular clusters, recovered as a declining power-law with slope 1.3 for streams above 1000 solar masses.
New simulation-based fitting formula for FDM halo mass functions at z=6-11, with ~30% weaker suppression than earlier formulas for m c²=10^{-21} eV at M~3e9 solar masses.
Simulations of dwarf galaxies show V/σ rising with stellar mass, with HI gas and young stars more rotation-supported than old stars.
FIRE-2 simulations with gravitational torque-driven and free-fall accretion models predict enough high-redshift AGN to explain little red dots, with a super-Eddington Eddington-limited scenario for M_BH >= 2e5 Msun in M_star >= 2e7 Msun galaxies reproducing key observations.
Bursty stellar feedback produces systematically flatter metallicity gradients than smooth feedback in high-redshift galaxies across multiple simulation suites.
FIRE-2 simulations find metallicity gradients in EoR galaxies flatten from median -0.15 dex/kpc at z~10 to -0.1 at z~6, with positive correlations to stellar mass and gas flow proxy Δv/2σ and links to central SFR density.
A large collaboration compiles and compares merger rate predictions for massive black holes across multiple galaxy formation models to forecast LISA detections and quantify uncertainties.
Comparisons of three cosmological simulations show HI-rich failed halos occupy different mass regimes and predict that more can be discovered locally in HI-poor environments rather than at high redshift.
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.
