GraphNPE recovers a significantly lower central density for Boötes I consistent with a core while Draco remains marginally cuspy, and demonstrates that higher-order velocity moments reduce bias in dynamical modeling.
SIDM simulations of dwarf halos show that quiescent merger histories produce gravothermal core collapse while sustained mergers prevent collapse and can yield central densities below gravothermal fluid model predictions.
Bursty stellar feedback produces systematically flatter metallicity gradients than smooth feedback in high-redshift galaxies across multiple simulation suites.
BonFIRE and CampFIRE simulations show bursty clustered star formation in early galaxies and predict UV luminosity functions matching observations at faint magnitudes with a turnover at M_UV approx -14 but overpredicting brighter galaxies.
