Distant Echoes of the Milky Way's Last Major Merger
Vedant Chandra, Rohan P. Naidu, Charlie Conroy +9
The majority of the Milky Way's stellar halo consists of debris from our Galaxy's last major merger, the Gaia-Sausage-Enceladus (GSE). In the past few years, stars from GSE have be…
Dwarf galaxy archaeology from chemical abundances and star formation histories
James W. Johnson, Charlie Conroy, Benjamin D. Johnson +8
We model the stellar abundances and ages of two disrupted dwarf galaxies in the Milky Way stellar halo: Gaia-Sausage Enceladus (GSE) and Wukong/LMS-1. Using a statistically robust…
The Stellar Halo of the Galaxy is Tilted & Doubly Broken
Jiwon Jesse Han, Charlie Conroy, Benjamin D. Johnson +7
Modern Galactic surveys have revealed an ancient merger that dominates the stellar halo of our Galaxy (\textit{Gaia}-Sausage-Enceladus, GSE). Using chemical abundances and kinemati…
Overview of the DESI Milky Way Survey
Andrew P. Cooper, Sergey E. Koposov, Carlos Allende Prieto +62
We describe the Milky Way Survey (MWS) that will be undertaken with the Dark Energy Spectroscopic Instrument (DESI) on the Mayall 4m telescope at the Kitt Peak National Observatory…
A Ghost in Boötes: The Least Luminous Disrupted Dwarf Galaxy
Vedant Chandra, Charlie Conroy, Nelson Caldwell +9
We report the discovery of Specter, a disrupted ultrafaint dwarf galaxy revealed by the H3 Spectroscopic Survey. We detected this structure via a pair of comoving metal-poor stars…
Live Fast, Die -Enhanced: The Mass-Metallicity- Relation of the Milky Way's Disrupted Dwarf Galaxies
Rohan P. Naidu, Charlie Conroy, Ana Bonaca +9
The Milky Way's satellite galaxies ("surviving dwarfs") have been studied for decades as unique probes of chemical evolution in the low-mass regime. Here we extend such studies to…
Birth of the Galactic Disk Revealed by the H3 Survey
Charlie Conroy, David H. Weinberg, Rohan P. Naidu +12
We use chemistry ([alpha/Fe] and [Fe/H]), main sequence turnoff ages, and kinematics determined from H3 Survey spectroscopy and Gaia astrometry to identify the birth of the Galacti…
A Tilt in the Dark Matter Halo of the Galaxy
Jiwon Jesse Han, Rohan P. Naidu, Charlie Conroy +9
Recent observations of the stellar halo have uncovered the debris of an ancient merger, Gaia-Sausage-Enceladus, estimated to have occurred ~8 Gyr ago. Follow-up studies have associ…
