Parameterizing the Standing Accretion Shock Instability for Inference with Galactic Supernova Neutrino Signals at IceCube
Dwaipayan Mukherjee, Mohamed Rameez, Basudeb Dasgupta
Simulations of core-collapse supernovae have revealed an epoch of hydrodynamic instability in which the matter of the collapsing star undergoes quasi-periodic oscillations, known a…
Some bivariate distributions on a discrete torus with application to wind direction datasets
Brajesh Kumar Dhakad, Jayant Jha, Debepsita Mukherjee
Many datasets are observed on a finite set of equally spaced directions instead of the exact angles, such as the wind direction data. However, in the statistical literature, bivari…
Sufficient and Necessary Conditions for Collective Neutrino Instability: Fast, Slow, and Mixed
Basudeb Dasgupta, Dwaipayan Mukherjee
Collective neutrino oscillations exhibit instabilities that induce appreciable flavor conversion, with crucial astrophysical implications. While the importance of initial phase-spa…
IceCube PeV neutrinos from heavy dark matter decay with 12 years HESE data
Diptarko Mukherjee, Ashadul Halder, Debasish Majumdar +1
The decay of superheavy dark matter from the early universe may undergo decay via QCD cascades and electroweak cascade to produce neutrinos as one of the decay products. We conside…
