Machine Learning the 6th Dimension: Stellar Radial Velocities from 5D Phase-Space Correlations
Adriana Dropulic, Bryan Ostdiek, Laura J. Chang +3
The Gaia satellite will observe the positions and velocities of over a billion Milky Way stars. In the early data releases, the majority of observed stars do not have complete 6D p…
An extended halo around an ancient dwarf galaxy
Anirudh Chiti, Anna Frebel, Joshua D. Simon +7
The Milky Way is surrounded by dozens of ultra-faint (< solar luminosities) dwarf satellite galaxies. They are the surviving remnants of the earliest galaxies, as confirmed…
Harnessing the Population Statistics of Subhalos to Search for Annihilating Dark Matter
Jean J. Somalwar, Laura J. Chang, Siddharth Mishra-Sharma +1
The Milky Way's dark matter halo is expected to host numerous low-mass subhalos with no detectable associated stellar component. Such subhalos are invisible unless their dark matte…
Foreground Mismodeling and the Point Source Explanation of the Fermi Galactic Center Excess
Malte Buschmann, Nicholas L. Rodd, Benjamin R. Safdi +4
The Fermi Large Area Telescope has observed an excess of ~GeV energy gamma rays from the center of the Milky Way, which may arise from near-thermal dark matter annihilation. Firmly…
Characterizing the Nature of the Unresolved Point Sources in the Galactic Center
Laura J. Chang, Siddharth Mishra-Sharma, Mariangela Lisanti +3
The Galactic Center Excess (GCE) of GeV gamma rays can be explained as a signal of annihilating dark matter or of emission from unresolved astrophysical sources, such as millisecon…
A Search for Dark Matter Annihilation in the Milky Way Halo
Laura J. Chang, Mariangela Lisanti, Siddharth Mishra-Sharma
The Milky Way halo is the brightest source of dark matter annihilation on the sky. Indeed, the potential strength of the Galactic dark matter signal can supersede that expected fro…
