Dwarf Galaxy Constraints on Interacting Fermionic Dark Matter
Bihag Dave, Raghuveer Garani
Dwarf galaxies in the Local Group offer a way to test dark matter (DM) models against stellar kinematic data. In this work, we study degenerate fermionic DM in two cases: the stand…

Compact Stars as Portals to Extra-Dimensional Dark Matter
Raghuveer Garani, Chris Kouvaris, Michel H. G. Tytgat +2
We investigate hydrostatic configurations of asymmetric dark matter (DM) spheres in scenarios where fermionic DM can propagate into extra spatial dimensions, while Standard Model f…

Particle production from inhomogeneities: general metric perturbations
Raghuveer Garani, Michele Redi, Andrea Tesi
We present universal formulas for particle production from gravitational inhomogeneities. In the massless limit the result is strikingly simple and completely determined by the two…
