Chiral transport of neutrinos in supernovae
EPJ Web of Conferences, 2017 The conventional neutrino transport theory for core-collapse supernovae misses one key property of neutrinos: the left-handedness. The chirality of neutrinos modifies the hydrodynamic behavior at the macroscopic scale and leads to topological transport ...

Neutrino-neutrino scattering and supernovae
The Astrophysical Journal, 1976 In the dense collapsing core of a star undergoing a supernova, electron-type neutrinos are produced by neutronization, and neutrino-antineutrino pairs of all types are produced by thermal processes. At some time the core plus an overlying mantle may become opaque to neutrinos, and large number densities of these particles may build up.

Detectability of the supernova relic neutrinos and neutrino oscillation [PDF]
Astroparticle Physics, 2003 We investigate the flux and the event rate of the supernova relic neutrino background (SRN) at the SuperKamiokande detector for various neutrino oscillation models with parameters inferred from recent experimental results. A realistic model of neutrino emission from supernova explosions and several models of the cosmic star formation history are ...

Heavy Elements and Electromagnetic Transients from Neutron Star Mergers
Annalen der Physik, Volume 536, Issue 2, February 2024.Astro‐(physics) has made major leaps forward through the combined information provided by both gravitational waves and electromagnetic emission from the first detected neutron star merger event. This review provides an up‐to‐date overview of today's understanding of neutron star mergers and their electromagnetic emission and it discusses possible ...

Supernova neutrinos and the LSND evidence for neutrino oscillations [PDF]
Physical Review D, 2002 The observation of the $\barν_e$ energy spectrum from a supernova burst can provide constraints on neutrino oscillations. We derive formulas for adiabatic oscillations of supernova antineutrinos for a variety of 3- and 4-neutrino mixing schemes and mass hierarchies which are consistent with the LSND evidence for $\barν_μ\to \barν_e$ oscillations ...

Neutrino Decay and the Supernova Relic Neutrino Background
Nuclear Physics B - Proceedings Supplements, 2005 The diffuse Supernova Relic Neutrino (SRN) background can be used, in principle, to probe neutrino decays with lifetimes of cosmological interest.

Nuclear astrophysicists at war
Natural Sciences, Volume 4, Issue 1, January 2024.The Manhattan program not only opened the path to the nuclear age for humans, but also triggered a lot of new questions and research directions in nuclear physics and astrophysics that still inform the ideas in these fields today. Abstract The question of energy production in stars stimulated an entire generation of young physicists in the 1930s who ...

Future Long-Baseline Neutrino Facilities and Detectors
Advances in High Energy Physics, 2013 We review the ongoing effort in the US, Japan, and Europe of the scientific community to study the location and the detector performance of the next-generation long-baseline neutrino facility. For many decades, research on the properties of neutrinos and

Nonstandard neutrino interactions in supernovae
Physical Review D, 2016 Nonstandard interactions (NSI) of neutrinos with matter can significantly alter neutrino flavor evolution in supernovae with the potential to impact explosion dynamics, nucleosynthesis, and the neutrinos signal. In this paper, we explore, both numerically and analytically, the landscape of neutrino flavor transformation effects in supernovae due to NSI
