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…
Modeling the Impact of Baryons on Subhalo Populations with Machine Learning
Ethan O. Nadler, Yao-Yuan Mao, Risa H. Wechsler +2
We identify subhalos in dark matter-only (DMO) zoom-in simulations that are likely to be disrupted due to baryonic effects by using a random forest classifier trained on two hydrod…
The Orbit and Origin of the Ultra-faint Dwarf Galaxy Segue 1
T. K. Fritz, M. Lokken, N. Kallivayalil +4
We present the first proper motion measurement for an ultra-faint dwarf spheroidal galaxy, Segue 1, using SDSS and LBC data as the first and second epochs separated by a baseline o…
The origin of ultra diffuse galaxies: stellar feedback and quenching
T. K. Chan, D. Kereš, A. Wetzel +5
We test if the cosmological zoom-in simulations of isolated galaxies from the FIRE project reproduce the properties of ultra diffuse galaxies. We show that stellar feedback-generat…
Modelling chemical abundance distributions for dwarf galaxies in the Local Group: the impact of turbulent metal diffusion
Ivanna Escala, Andrew Wetzel, Evan N. Kirby +6
We investigate stellar metallicity distribution functions (MDFs), including Fe and -element abundances, in dwarf galaxies from the Feedback in Realistic Environments (FIRE) proj…
