The effect of models of the interstellar media on the central mass distribution of galaxies
Charlotte Christensen, Fabio Governato, Thomas Quinn +5
We compare the central mass distribution of galaxies simulated with three different models of the interstellar medium (ISM) with increasing complexity: primordial (H+He) cooling do…
Constraints on the Shape of the Milky Way Dark Matter Halo from Jeans Equations Applied to SDSS Data
Sarah R. Loebman, Zeljko Ivezic, Thomas R. Quinn +4
We search for evidence of dark matter in the Milky Way by utilizing the stellar number density distribution and kinematics measured by the Sloan Digital Sky Survey (SDSS) to helioc…
Reproducing the Stellar Mass/Halo Mass Relation in Simulated LCDM Galaxies: Theory vs Observational Estimates
Ferah Munshi, F. Governato, A. M. Brooks +6
We examine the present-day total stellar-to-halo mass (SHM) ratio as a function of halo mass for a new sample of simulated field galaxies using fully cosmological, LCDM, high resol…
A Baryonic Solution to the Missing Satellites Problem
Alyson M. Brooks, Michael Kuhlen, Adi Zolotov +1
It has been demonstrated that the inclusion of baryonic physics can alter the dark matter densities in the centers of low-mass galaxies, making the central dark matter slope more s…
Why Baryons Matter: The Kinematics of Dwarf Spheroidal Satellites
Alyson M. Brooks, Adi Zolotov
We use high resolution cosmological simulations of Milky Way-mass galaxies that include both baryons and dark matter to show that baryonic physics (energetic feedback from supernov…
Baryons Matter: Why Luminous Satellite Galaxies Have Reduced Central Masses
Adi Zolotov, Alyson M. Brooks, Beth Willman +7
Using high resolution cosmological hydrodynamical simulations of Milky Way-massed disk galaxies, we demonstrate that supernovae feedback and tidal stripping lower the central masse…
