Understanding and visualizing the statistical analysis of SN1987A neutrino data
European Physical Journal C: Particles and Fields, 2022 The SN1987A detection through neutrinos was an event of great importance in neutrino physics, being the first detection of neutrinos created outside our solar system, and then inaugurating the era of experimental neutrino astronomy.

Mini Z' Burst from Relic Supernova Neutrinos and Late Neutrino Masses
, 2006 In models in which neutrinos are light, due to a low scale of symmetry breaking, additional light bosons are generically present. We show that the interaction between diffuse relic supernova neutrinos (RSN) and the cosmic background neutrinos, via ...

Dark Energy From the Gravitational Wave Background With Scalar Field Dark Matter
Astronomische Nachrichten, Volume 346, Issue 3-4, March-May 2025.ABSTRACT Recent observational results, such as those from pulsar timing arrays (PTA), suggest a low‐frequency Gravitational Wave Background (GWB) permeates our universe. This opens the possibility that gravitational waves could span a broader spectrum, potentially impacting cosmological scales.

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.

A Brief, Biased View of Neutron Star Cooling
Astronomische Nachrichten, Volume 346, Issue 1, January 2025.ABSTRACT This is a concise and non‐technical review of topics related to neutron star (NS) cooling, for both young NSs and NSs in low‐mass x‐ray binaries. Neutrino emission from the NS core drives cooling rates, via different processes including Urca processes and pair breaking and formation at the neutron superfluid critical temperature.

Dark matter sterile neutrinos in stellar collapse: alteration of energy/lepton number transport and a mechanism for supernova explosion enhancement [PDF]
, 2006 We investigate matter-enhanced Mikheyev-Smirnov-Wolfenstein (MSW) active-sterile neutrino conversion in the $\nu_e \rightleftharpoons \nu_s$ channel in the collapse of the iron core of a pre-supernova star.

Convoluted ν-Signals on 114Cd Isotope from Astrophysical and Laboratory Neutrino Sources
Advances in High Energy Physics, 2015 At first, we evaluate scattering cross sections of low, and intermediate-energy neutrinos scattered off the 114 Cd isotope, the most abundant Cd isotope present also in the COBRA detector (CdTe and CdZnTe materials) which aims to search for double beta ...
