Stability of Collective Neutrino Oscillations -- A Distributional Approach
Rupak Majumder, Dwaipayan Mukherjee, Shamik Gupta +1
We study the stability of collective neutrino oscillations using a distributional approach motivated by the statistical mechanics of Kuramoto synchronization. Treating the ensemble…
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…
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…
Stronger Constraints on Primordial Black Holes as Dark Matter Derived from the Thermal Evolution of the Intergalactic Medium over the Last Twelve Billion Years
Nabendu Kumar Khan, Anupam Ray, Girish Kulkarni +1
Primordial black holes (PBHs) have been explored as potential dark matter candidates, with various astrophysical observations placing upper limits on the fraction …
Constraining Asymmetric Dark Matter using Colliders and Direct Detection
Arnab Roy, Basudeb Dasgupta, Monoranjan Guchait
We reappraise the viability of asymmetric dark matter (ADM) realized as a Dirac fermion coupling dominantly to the Standard Model fermions. Treating the interactions of such a DM p…
Light Shining Through Wall Bounds on Axions From Obscured Magnetars
Dibya S. Chattopadhyay, Basudeb Dasgupta, Amol Dighe +1
Coupling of axions or axion-like particles (ALPs) with photons may lead to photons escaping optically opaque regions by oscillating into ALPs. This phenomenon may be viewed as the…
