Detection of supernova neutrinos with neutrino-iron scattering [PDF]

open access: yesPhysical Review C, 2008
The $ν_e-^{56}$Fe cross section is evaluated in the projected quasiparticle random phase approximation (PQRPA). This model solves the puzzle observed in RPA for nuclei with mass around $^{12}$C, because it is the only RPA model that treats the Pauli principle correctly.

Neutrinoloser Doppelbetazerfall: Der Gral der Neutrinophysik

open access: yesPhysik in unserer Zeit, Volume 56, Issue 3, Page 132-137, May 2025.
Die Entschlüsselung der Neutrinoeigenschaften ist auch siebzig Jahre nach ihrer Entdeckung noch nicht abgeschlossen. Es wäre eine spektakuläre Entdeckung, sollten Neutrinos ihre eigenen Antiteilchen sein und sich folglich als Majorana‐Teilchen entpuppen. Mehrere Experimente untersuchen diese Möglichkeit.

Dark Energy From the Gravitational Wave Background With Scalar Field Dark Matter

open access: yesAstronomische 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.

Supernova Neutrino Neutrino Astronomy

open access: yes, 2018
Modern neutrino facilities will be able to detect a large number of neutrinos from the next Galactic supernova. We investigate the viability of the triangulation method to locate a core-collapse supernova by employing the neutrino arrival time differences at various detectors.

Convoluted ν-Signals on 114Cd Isotope from Astrophysical and Laboratory Neutrino Sources

open access: yesAdvances 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 ...

A Brief, Biased View of Neutron Star Cooling

open access: yesAstronomische 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.

Supernova neutrino detection in Borexino [PDF]

open access: yesAstroparticle Physics, 2002
We calculated the expected neutrino signal in Borexino from a typical Type II supernova at a distance of 10 kpc. A burst of around 110 events would appear in Borexino within a time interval of about 10 s. Most of these events would come from the reaction channel $\barν_e+p\to e^++n$, while about 30 events would be induced by the interaction of the ...

Combined Pre-supernova Alert System with KamLAND and Super-Kamiokande

open access: yesThe Astrophysical Journal
Preceding a core-collapse supernova (CCSN), various processes produce an increasing amount of neutrinos of all flavors characterized by mounting energies from the interior of massive stars.

Cosmic-Ray Boosted Diffuse Supernova Neutrinos

open access: yesAstronomy
The subject of boosted fluxes of dark matter or cosmic relic neutrinos via scattering on cosmic rays has received considerable attention recently. This article investigates the boosted neutrino flux from the scattering of cosmic rays and the so-far ...
