The origin of the diverse morphologies and kinematics of Milky Way-mass galaxies in the FIRE-2 simulations
Shea Garrison-Kimmel, Philip F. Hopkins, Andrew Wetzel +11
We use hydrodynamic cosmological zoom-in simulations from the FIRE project to explore the morphologies and kinematics of fifteen Milky Way (MW)-mass galaxies. Our sample ranges fro…
Global Properties of M31's Stellar Halo from the SPLASH Survey: III. Measuring the Stellar Velocity Dispersion Profile
Karoline M. Gilbert, Erik Tollerud, Rachael L. Beaton +7
We present the velocity dispersion of red giant branch (RGB) stars in M31's halo, derived by modeling the line of sight velocity distribution of over 5000 stars in 50 fields spread…
Through a Smoother Lens: An expected absence of LCDM substructure detections from hydrodynamic and dark matter only simulations
Andrew S. Graus, James S. Bullock, Michael Boylan-Kolchin +1
A fundamental prediction of the cold dark matter cosmology is the existence of a large number of dark subhalos around galaxies, most of which should be entirely devoid of stars. Co…
The Lopsidedness of Satellite Galaxy Systems in CDM simulations
Marcel S. Pawlowski, Rodrigo A. Ibata, James S. Bullock
The spatial distribution of satellite galaxies around pairs of galaxies in the Sloan Digital Sky Survey (SDSS) have been found to bulge significantly towards the respective partner…
Space Motions of the Dwarf Spheroidal Galaxies Draco and Sculptor based on HST Proper Motions with ~10-year Time Baseline
Sangmo Tony Sohn, Ekta Patel, Gurtina Besla +5
We present new proper motion (PM) measurements of the dwarf spheroidal galaxies (dSphs) Draco and Sculptor using multi-epoch images obtained with the Hubble Space Telescope ACS/WFC…
SIDM on FIRE: Hydrodynamical Self-Interacting Dark Matter simulations of low-mass dwarf galaxies
Victor H. Robles, James S. Bullock, Oliver D. Elbert +7
We compare a suite of four simulated dwarf galaxies formed in 10 haloes of collisionless Cold Dark Matter (CDM) with galaxies simulated in the same haloes with an…
Dwarf Galaxy Mass Estimators vs. Cosmological Simulations
Alejandro Gonzalez-Samaniego, James S. Bullock, Michael Boylan-Kolchin +5
We use a suite of high-resolution cosmological dwarf galaxy simulations to test the accuracy of commonly-used mass estimators from Walker et al.(2009) and Wolf et al.(2010), both o…
Counting Black Holes: The Cosmic Stellar Remnant Population and Implications for LIGO
Oliver D. Elbert, James S. Bullock, Manoj Kaplinghat
We present an empirical approach for interpreting gravitational wave signals of binary black hole mergers under the assumption that the underlying black hole population is sourced…
FIRE-2 Simulations: Physics versus Numerics in Galaxy Formation
Philip F Hopkins, Andrew Wetzel, Dusan Keres +25
The Feedback In Realistic Environments (FIRE) project explores feedback in cosmological galaxy formation simulations. Previous FIRE simulations used an identical source code (FIRE-…
Not so lumpy after all: modeling the depletion of dark matter subhalos by Milky Way-like galaxies
Shea Garrison-Kimmel, Andrew R. Wetzel, James S. Bullock +8
Among the most important goals in cosmology is detecting and quantifying small () dark matter (DM) subhalos. Current probes around the…
