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…
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…
Dynamical evidence for a strong tidal interaction between the Milky Way and its satellite, Leo V
Michelle L. M. Collins, Erik J. Tollerud, David J. Sand +3
We present a chemodynamical analysis of the Leo~V dwarf galaxy, based on Keck II DEIMOS spectra of 8 member stars. We find a systemic velocity for the system of $\langle v_r\rangle…
Milky Way Mass and Potential Recovery Using Tidal Streams in a Realistic Halo
Ana Bonaca, Marla Geha, Andreas H. W. Kuepper +3
We present a new method for determining the Galactic gravitational potential based on forward modeling of tidal stellar streams. We use this method to test the performance of smoot…
