Neutrino and Positron Constraints on Spinning Primordial Black Hole Dark Matter
Basudeb Dasgupta, Ranjan Laha, Anupam Ray
Primordial black holes can have substantial spin -- a fundamental property that has a strong effect on its evaporation rate. We conduct a comprehensive study of the detectability o…

Dark matter capture in celestial objects: Improved treatment of multiple scattering and updated constraints from white dwarfs
Basudeb Dasgupta, Aritra Gupta, Anupam Ray
We revisit dark matter (DM) capture in celestial objects, including the impact of multiple scattering, and obtain updated constraints on the DM-proton cross section using observati…
