Seltene und extreme Supernovae

Physik in unserer Zeit, Volume 55, Issue 1, Page 40-46, January 2024.
Robotische Teleskope entdecken eine zunehmende Vielfalt transienter Strahlungsquellen, deren ungewöhnliche Eigenschaften neue Arten von Sternexplosionen nahelegen. Obwohl die absolute Häufigkeit solcher Ereignisse sehr klein ist, erlaubt ihre extreme Helligkeit relativ häufige Sichtungen, stellt aber theoretische Modelle vor große Herausforderungen ...

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.

Probing non-standard neutrino interactions with a light boson from next galactic and diffuse supernova neutrinos

Journal of High Energy Physics, 2022
Non-standard neutrino interactions with a massive boson can produce the bosons in the core of core-collapse supernovae (SNe). After the emission of the bosons from the SN core, their subsequent decays into neutrinos can modify the SN neutrino flux.

Pre-Supernova (Anti)Neutrino Emission Due to Weak-Interaction Reactions with Hot Nuclei

Particles
Reliable predictions of (anti)neutrino spectra and luminosities are essential for assessing the feasibility of detecting pre-supernova neutrinos. Using the stellar evolution code MESA, we calculate the (anti)neutrino spectra and luminosities under ...

Supernova neutrino detection in LZ [PDF]

Journal of Instrumentation, 2018
In the first 10 seconds of a core-collapse supernova, almost all of its progenitor's gravitational potential, O(10$^{53}$~ergs), is carried away in the form of neutrinos. These neutrinos, with O(10~MeV) kinetic energy, can interact via coherent elastic neutrino-nucleus scattering (CE$ν$NS) depositing O(1~keV) in detectors.

Ghost particles in the universe: Neutrinos in astrophysics and cosmology

Mètode Science Studies Journal: Annual Review, 2017
  Neutrinos are nearly massless and very difficult to detect because they interact so very weakly. Sixty years after seeing the first of these «ghost particles» we know a lot about their properties.

Nuclear Neutrino Spectra in Late Stellar Evolution

EPJ Web of Conferences, 2018
Neutrinos are the principle carriers of energy in massive stars, beginning from core carbon burning and continuing through core collapse and after the core bounce. In fact, it may be possible to detect neutrinos from nearby pre-supernova stars. Therefore,
