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…
Velocity Dispersion of the GD-1 Stellar Stream
Megan T. Gialluca, Rohan P. Naidu, Ana Bonaca
Tidally dissolved globular clusters form thin stellar streams that preserve a historical record of their past evolution. We report a radial velocity dispersion of $2.3\pm0.3\,\text…
Discovery of Magellanic Stellar Debris in the H3 Survey
Dennis Zaritsky, Charlie Conroy, Rohan P. Naidu +9
We report the discovery of 15 stars in the H3 survey that lie, in projection, near the tip of the trailing gaseous Magellanic Stream (MS). The stars have Galactocentric velocities…
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…
Evidence from the H3 Survey that the Stellar Halo is Entirely Comprised of Substructure
Rohan P. Naidu, Charlie Conroy, Ana Bonaca +5
In the CDM paradigm the Galactic stellar halo is predicted to harbor the accreted debris of smaller systems. To identify these systems, the H3 Spectroscopic Survey, combined wit…
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…
High-resolution spectroscopy of the GD-1 stellar stream localizes the perturber near the orbital plane of Sagittarius
Ana Bonaca, Charlie Conroy, David W. Hogg +6
The -long thin stellar stream in the Milky Way halo, GD-1, has an ensemble of features that may be due to dynamical interactions. Using high-resolution MMT/Hectochelle s…
