The DREAMS Project: Disentangling the Impact of Halo-to-Halo Variance and Baryonic Feedback on Milky Way Dark Matter Density Profiles

Alex M. Garcia, Jonah C. Rose, Paul Torrey +23

In this work, we utilize a new suite of Milky Way-mass halos from the DREAMS Project, simulated with Cold Dark Matter (CDM), to quantify the influence of baryon feedback and intrin…

On the sensitivity of different galaxy properties to warm dark matter

Belén Costanza, Bonny Y. Wang, Francisco Villaescusa-Navarro +7

We study the impact of warm dark matter (WDM) particle mass on galaxy properties using 1,024 state-of-the-art cosmological hydrodynamical simulations from the DREAMS project. We be…
