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 ...

Supernova bound on keV-mass sterile neutrinos

, 2011
In this talk, I first explain why the keV-mass sterile neutrinos, slightly mixing with ordinary neutrinos, are interesting in particle astrophysics.

KamLAND Sensitivity to Neutrinos from Pre-Supernova Stars [PDF]

, 2016
In the late stages of nuclear burning for massive stars (M > 8 M⊙), the production of neutrino–antineutrino pairs through various processes becomes the dominant stellar cooling mechanism.

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 [PDF]

, 2003
We propose that neutrino-proton elastic scattering, {nu} + p {yields} {nu} + p, can be used for the detection of supernova neutrinos. Though the proton recoil kinetic energy spectrum is soft, with T{sub p} {approx_equal} 2E{sub {nu}}{sup 2}/M{sub p}, and

Primer on Axion Physics

Annalen der Physik, Volume 536, Issue 1, January 2024.
A primer on axion physics, emphasizing an intuitive understanding of why the axion solves the strong CP problem. Abstract The canonical axion potential is reviewed, with an emphasis on the field theory underlying radial and angular modes of complex scalar fields.

Triggering on Supernova Burst Neutrinos at DUNE

, 2018
Liquid Argon Time Projection Chambers (LArTPCs) are sensitive to low energy electron neutrinos via a charged current interaction on argon. The Deep Underground Neutrino Experiment’s (DUNE’s) 40kt far detector at the Homestake mine in South Dakota will ...

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 ...

Dynamic neutrino mass ordering and its imprint on the diffuse supernova neutrino background

European Physical Journal C: Particles and Fields
Neutrino masses may have evolved dynamically throughout the history of the Universe, potentially leading to a mass spectrum distinct from the normal or inverted ordering observed today.
