Low-Energy Signals from the Formation of Dark Matter-Nuclear Bound States
Asher Berlin, Hongwan Liu, Maxim Pospelov +1
Dark matter particles may bind with nuclei if there exists an attractive force of sufficient strength. We show that a dark photon mediator of mass MeV that kineti…
Joint CMB and BBN Constraints on Light Dark Sectors with Dark Radiation
Cara Giovanetti, Mariangela Lisanti, Hongwan Liu +1
Dark sectors provide a compelling theoretical framework for thermally producing sub-GeV dark matter, and motivate an expansive new accelerator and direct-detection experimental pro…
New Thermal Relic Targets for Inelastic Vector-Portal Dark Matter
Patrick J. Fitzpatrick, Hongwan Liu, Tracy R. Slatyer +1
We examine the vector-portal inelastic dark matter (DM) model with DM mass and dark photon mass , in the `forbidden dark matter' regime where $1 \lesssim m_{A'}/m_χ\l…
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…
