The Observable Properties of Galaxy Accretion Events in Milky Way–like Galaxies in the FIRE-2 Cosmological Simulations
Abstract In the Λ-Cold Dark Matter model of the universe, galaxies form in part through
accreting satellite systems. Previous works have built an understanding of the signatures of …

The Next Generation Virgo Cluster Survey (NGVS). XXXV. First Kinematical Clues of Overly Massive Dark Matter Halos in Several Ultradiffuse Galaxies in the Virgo …
We present Keck/DEIMOS spectroscopy of the first complete sample of ultradiffuse galaxies
(UDGs) in the Virgo cluster. We select all UDGs in Virgo that contain at least 10 globular …

Quantifying the Stellar Halo's Response to the LMC's Infall with Spherical Harmonics
EC Cunningham, N Garavito-Camargo… - The Astrophysical …, 2020 - iopscience.iop.org
The vast majority of the mass in the Milky Way (MW) is in dark matter (DM); we therefore
cannot directly observe the MW mass distribution and have to use tracer populations in …

The Baltimore Oriole's Nest: Cool Winds from the Inner and Outer Parts of a Star-forming Galaxy at z= 1.3
Strong galactic winds are ubiquitous at z≳ 1. However, it is not well-known where inside
galaxies these winds are launched from. We study the cool winds (∼ 10 4 K) in two spatial …
