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…
Reconciling observed and simulated stellar halo masses
Robyn E. Sanderson, Shea Garrison-Kimmel, Andrew Wetzel +6
We use cosmological hydrodynamical simulations of Milky-Way-mass galaxies from the FIRE project to evaluate various strategies for estimating the mass of a galaxy's stellar halo fr…
Astrometry with the Wide-Field InfraRed Space Telescope
Robyn E. Sanderson, Andrea Bellini, Stefano Casertano +14
The Wide-Field InfraRed Space Telescope (WFIRST) will be capable of delivering precise astrometry for faint sources over the enormous field of view of its main camera, the Wide-Fie…
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…
