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…
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…
Orbital Clustering Identifies the Origins of Galactic Stellar Streams
Ana Bonaca, Rohan P. Naidu, Charlie Conroy +9
The origins of most stellar streams in the Milky Way are unknown. With improved proper motions provided by Gaia EDR3, we show that the orbits of 23 Galactic stellar streams are hig…
Ancient Very Metal-Poor Stars Associated With the Galactic Disk in the H3 Survey
Courtney Carter, Charlie Conroy, Dennis Zaritsky +8
Ancient, very metal-poor stars offer a window into the earliest epochs of galaxy formation and assembly. We combine data from the H3 Spectroscopic Survey and Gaia to measure metall…
A Diffuse Metal-Poor Component of the Sagittarius Stream Revealed by the H3 Survey
Benjamin D. Johnson, Charlie Conroy, Rohan P. Naidu +6
The tidal disruption of the Sagittarius dwarf galaxy has generated a spectacular stream of stars wrapping around the entire Galaxy. We use data from and the H3 Stellar Spect…
Timing the Early Assembly of the Milky Way with the H3 Survey
Ana Bonaca, Charlie Conroy, Phillip A. Cargile +7
The archaeological record of stars in the Milky Way opens a uniquely detailed window into the early formation and assembly of galaxies. Here we use 11,000 main-sequence turn-off st…
