Dark Matter Substructure under the Electron Scattering Lamppost
Jatan Buch, Manuel A. Buen-Abad, JiJi Fan +1
We study the mutual relationship between dark matter-electron scattering experiments and possible new dark matter substructure nearby hinted by the Gaia data. We show how kinematic…
Galactic Origin of Relativistic Bosons and XENON1T Excess
Jatan Buch, Manuel A. Buen-Abad, JiJi Fan +1
We entertain the exotic possibility that dark matter (DM) decays or annihilations taking place in our galaxy may produce a flux of relativistic very weakly-coupled bosons, axions o…
Implications of the Gaia Sausage for Dark Matter Nuclear Interactions
Jatan Buch, JiJi Fan, John Shing Chau Leung
The advent of the Gaia era has led to potentially revolutionary understanding of dark matter (DM) dynamics in our galaxy, which has important consequences for direct detection (DD)…
Using Gaia DR2 to Constrain Local Dark Matter Density and Thin Dark Disk
Jatan Buch, John Shing Chau Leung, JiJi Fan
We use stellar kinematics from the latest Gaia data release (DR2) to measure the local dark matter density in a heliocentric cylinder of radius and…
