Neutrino quantum kinetics in three flavors
Shashank Shalgar, Irene Tamborra
The impact of neutrino flavor conversion on the supernova mechanism is yet to be fully understood. We present multi-energy and multi-angle solutions of the neutrino quantum kinetic…
Can we ignore the time dependence in matter neutrino resonance?
Owais Ullah Faiz, Mushahid Hussain, Shashank Shalgar
In the vicinity of neutron star mergers (NSMs), it is possible for the neutrino self-interaction potential to cancel with the matter potential leading to matter neutrino resonance…
Electron-neutrino lepton number crossings: Variations with the supernova core physics
Marie Cornelius, Irene Tamborra, Malte Heinlein +2
A crucial ingredient affecting fast neutrino flavor conversion in core-collapse supernovae (SNe) is the shape of the angular distribution of the electron-neutrino lepton number (EL…
Robustness of Solutions of the Quantum Kinetic Equations in the Presence of Matter Density Fluctuations
Shashank Shalgar, Mariam Gogilashvili
We investigate the role of fluctuations in the matter density on neutrino flavor evolution by studying their effects on the collision terms in the spherically symmetric quantum kin…
Position drift with Gaia
Andreas Tsigkas Kouvelis, Asta Heinesen, Shashank Shalgar +1
The proper motion (also known as position drift) field of extragalactic sources at cosmological distances across our sky can be used to measure the acceleration of the Solar System…
Non-conservation of Lepton Numbers in the Neutrino Sector Could Change the Prospects for Core Collapse Supernova Explosions
Anna M. Suliga, Patrick Chi-Kit Cheong, Julien Froustey +5
We show that interactions violating the conservation of lepton numbers in the neutrino sector could significantly alter the standard low entropy picture for the pre-supernova colla…
