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…
