From Capture to Collapse: Revisiting Black Hole formation by Fermionic Asymmetric Dark Matter in Neutron Stars
Sandra Robles, Drona Vatsyayan, Giorgio Busoni
Fermionic asymmetric dark matter (ADM) can be captured in neutron stars (NSs) via scatterings with the star constituents. The absence of dark matter annihilation due to its asymmet…

Large neutrino mass in cosmology and keV sterile neutrino dark matter from a dark sector
Cristina Benso, Thomas Schwetz, Drona Vatsyayan
We consider an extended seesaw model which generates active neutrino masses via the usual type-I seesaw and leads to a large number of massless fermions as well as a sterile neutri…
