Can We Constrain Warm Dark Matter Masses with Individual Galaxies?
The Astrophysical JournalWe study the impact of warm dark matter (WDM) mass on the internal properties of individual galaxies using a large suite of 1024 state-of-the-art cosmological hydrodynamic simulations from the DREAMS project.

New Galaxy UV Luminosity Constraints on Warm Dark Matter from JWST
The Astrophysical JournalWe exploit the recent James Webb Space Telescope (JWST) determination of galaxy UV luminosity functions over the redshift range z = 9–14.5 to derive constraints on warm dark matter (WDM) models. The delayed structure formations in WDM universes make high-
