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…
Discrete Effects in Stellar Feedback: Individual Supernovae, Hypernovae, and IMF Sampling in Dwarf Galaxies
Kung-Yi Su, Philip F. Hopkins, Christopher C. Hayward +6
Using high-resolution simulations from the FIRE-2 (Feedback In Realistic Environments) project, we study the effects of discreteness in stellar feedback processes on the evolution…
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…
The MOSDEF Survey: Broad Emission Lines at z=1.4-3.8
William R. Freeman, Brian Siana, Mariska Kriek +12
We present results from the MOSFIRE Deep Evolution Field (MOSDEF) survey on broad flux from the nebular emission lines H, [NII], [OIII], H, and [SII]. The sample consists of…
Stacked star formation rate profiles of bursty galaxies exhibit 'coherent' star formation
Matthew E. Orr, Christopher C. Hayward, Erica J. Nelson +6
In a recent work based on 3200 stacked H maps of galaxies at , Nelson et al.~find evidence for `coherent star formation': the stacked SFR profiles of galaxies above (b…
Testing the Recovery of Intrinsic Galaxy Sizes and Masses of z~2 Massive Galaxies Using Cosmological Simulations
Sedona H. Price, Mariska Kriek, Robert Feldmann +5
Accurate measurements of galaxy masses and sizes are key to tracing galaxy evolution over time. Cosmological zoom-in simulations provide an ideal test bed for assessing the recover…
How To Model Supernovae in Simulations of Star and Galaxy Formation
Philip F. Hopkins, Andrew Wetzel, Dusan Keres +6
We study the implementation of mechanical feedback from supernovae (SNe) and stellar mass loss in galaxy simulations, within the Feedback In Realistic Environments (FIRE) project.…
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…
Gaia reveals a metal-rich in-situ component of the local stellar halo
Ana Bonaca, Charlie Conroy, Andrew Wetzel +2
We use the first Gaia data release, combined with RAVE and APOGEE spectroscopic surveys, to investigate the origin of halo stars within <~3 kpc from the Sun. We identify halo stars…
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…
