A core-collapse supernova (CCSN) provides a unique astrophysical site for studying neutrino–matter interactions. Prior to the shock-breakout neutrino burst during the collapse of the iron core, a preshock ν e burst arises from the electron capture of nuclei and it is sensitive to the low-energy coherent elastic neutrino–nucleus scattering (CEνNS) which dominates the neutrino opacity. Since the CEνNS depends strongly on nonstandard neutrino interactions (NSIs), which are completely beyond the…

AN OPEN-SOURCE NEUTRINO RADIATION HYDRODYNAMICS CODE FOR CORE-COLLAPSE SUPERNOVAE
We present an open-source update to the spherically-symmetric, general-relativistic hydrodynamics, core-collapse supernova (CCSN) code GR1D (O'Connor & Ott, 2010, CQG, 27, 114103). The source code is
sntools: An event generator for supernova burst neutrinos
Observing the neutrino signal from the next galactic supernova can help solve this puzzle. To prepare for this once-in-a-lifetime event, it is essential to study how various detectors respond to the
RELATIVISTIC EQUATION OF STATE FOR CORE-COLLAPSE SUPERNOVA SIMULATIONS
We construct the equation of state (EOS) of dense matter covering a wide range of temperature, proton fraction, and density for the use of core-collapse supernova simulations. The study is based on
Core-collapse supernova explosion theory
TLDR
The delayed neutrino-heating mechanism is emerging as the key driver of supernova explosions, but there remain many issues to address, such as the chaos of the involved dynamics.
Observation of coherent elastic neutrino-nucleus scattering
TLDR
The coherent elastic scattering of neutrinos off nuclei has eluded detection for four decades, but this mode of interaction offers new opportunities to study neutrino properties and leads to a miniaturization of detector size, with potential technological applications.
