Fast Flavor Depolarization of Supernova Neutrinos
Soumya Bhattacharyya, Basudeb Dasgupta
Flavor-dependent neutrino emission is critical to the evolution of a supernova and its neutrino signal. In the dense anisotropic interior of the star, neutrino-neutrino forward-sca…
Low Mass Black Holes from Dark Core Collapse
Basudeb Dasgupta, Ranjan Laha, Anupam Ray
Unusual masses of black holes being discovered by gravitational wave experiments pose fundamental questions about the origin of these black holes. Black holes with masses smaller t…
Dark matter capture in celestial objects: light mediators, self-interactions, and complementarity with direct detection
Basudeb Dasgupta, Aritra Gupta, Anupam Ray
We generalize the formalism for DM capture in celestial bodies to account for arbitrary mediator mass, and update the existing and projected astrophysical constraints on DM-nucleon…
Fast Neutrino Flavor Conversion at Late Time
Soumya Bhattacharyya, Basudeb Dasgupta
We study the fully nonlinear fast flavor evolution of neutrinos in 1+1 dimensions. Our numerical analysis shows that at late time the system reaches an approximately steady state.…
Fast Neutrino Flavor Instability in the Neutron-star Convection Layer of Three-dimensional Supernova Models
Robert Glas, H. -Thomas Janka, Francesco Capozzi +4
Neutrinos from a supernova (SN) might undergo fast flavor conversions near the collapsed stellar core. We perform a detailed study of this intriguing possibility, analyzing time-de…
