Star-forming galaxies as the origin of IceCube neutrinos: Reconciliation with Fermi-LAT gamma rays
Sovan Chakraborty, Ignacio Izaguirre
Cosmic ray accelerators like supernova and hypernova remnants in star forming galaxies are one of the most plausible sources of the IceCube observed diffuse astrophysical neutrinos…
Detecting supernova neutrinos with iron and lead detectors
Abhijit Bandyopadhyay, Pijushpani Bhattacharjee, Sovan Chakraborty +2
Supernova (SN) neutrinos can excite the nuclei of various detector materials beyond their neutron emission thresholds through charged current (CC) and neutral current (NC) interact…
Probing axions with the neutrino signal from the next galactic supernova
Tobias Fischer, Sovan Chakraborty, Maurizio Giannotti +3
We study the impact of axion emission in simulations of massive star explosions, as an additional source of energy loss complementary to the standard neutrino emission. The inclusi…
Self-induced neutrino flavor conversion without flavor mixing
Sovan Chakraborty, Rasmus Sloth Hansen, Ignacio Izaguirre +1
Neutrino-neutrino refraction in dense media can cause self-induced flavor conversion triggered by collective run-away modes of the interacting flavor oscillators. The growth rates…
Collective neutrino flavor conversion: Recent developments
Sovan Chakraborty, Rasmus Sloth Hansen, Ignacio Izaguirre +1
Neutrino flavor evolution in core-collapse supernovae, neutron-star mergers, or the early universe is dominated by neutrino-neutrino refraction, often spawning "self-induced flavor…
