Fast flavor conversions of supernova neutrinos: Classifying instabilities via dispersion relations [PDF]

open access: yes, 2017
Supernova neutrinos can exhibit a rich variety of flavor conversion mechanisms. In particular, they can experience "fast" self-induced flavor conversions almost immediately above the core.

Lifting the core-collapse supernova bounds on keV-mass sterile neutrinos [PDF]

open access: yesJournal of Cosmology and Astroparticle Physics, 2020
We explore the energy and entropy transport as well as the lepton number variation induced from the mixing between electron and sterile neutrinos with keV mass in the supernova core.

Von Wasserstoff bis Eisen, Nickel und Zink

open access: yesPhysik in unserer Zeit, Volume 53, Issue 4, Page 182-189, July 2022., 2022
Woraus besteht die Welt? Die Philosophen der Antike postulierten vier oder fünf Elemente. In der Neuzeit erweiterten Dimitri Mendelejew und Lothar Meyer dies auf eine rasch wachsende Tabelle der chemischen Elemente. Kirchhoff und Bunsen entdeckten Fraunhofer‐Linien im Sonnenspektrum, denen zufolge die auf der Erde existierenden Elemente auch in Sternen

Implementation and first results of the KM3NeT real-time core-collapse supernova neutrino search

open access: yesEuropean Physical Journal C: Particles and Fields, 2022
The KM3NeT research infrastructure is unconstruction in the Mediterranean Sea. KM3NeT will study atmospheric and astrophysical neutrinos with two multi-purpose neutrino detectors, ARCA and ORCA, primarily aimed at GeV–PeV neutrinos.

Unconventional reconciliation path for quantum mechanics and general relativity

open access: yesIET Quantum Communication, Volume 3, Issue 2, Page 99-111, June 2022., 2022
Abstract Physics in general is successfully governed by quantum mechanics at the microscale and principles of relativity at the macroscale. Any attempts to unify them using conventional methods have somewhat remained elusive for nearly a century up to the present stage. Here, a classical gedanken experiment of electron‐wave diffraction of a single slit

Neutrinos from Supernovas and Supernova Remnants [PDF]

open access: yesAIP Conference Proceedings, 2005
Supernovae (SN) and supernova remnants (SNR) have key roles in galaxies, but their physical descriptions is still incomplete. Thus, it is of interest to study neutrino radiation to understand SN and SNR better. We will discuss: (1) The ~10 MeV thermal neutrinos that arise from core collapse SN, that were observed for SN1987A, and can be seen with ...

Earth Matter Effects in Detection of Supernova Neutrinos [PDF]

open access: yes, 2006
We calculated the matter effect, including both the Earth and supernova, on the detection of neutrinos from type II supernovae at the proposed Daya Bay reactor neutrino experiment.

Charged-Current Neutrino-Nucleus Scattering off the Even Molybdenum Isotopes

open access: yesAdvances in High Energy Physics, 2012
Neutrinos from supernovae constitute important probes of both the currently unknown supernova mechanisms and of neutrino properties. Reliable information about the nuclear responses to supernova neutrinos is therefore crucial.

Searching for high-energy neutrinos from the most luminous supernovae with the IceCube Neutrino Observatory [PDF]

open access: yesEPJ Web of Conferences, 2023
The sources of the astrophysical neutrino flux discovered by IceCube remain for the most part unresolved. Extragalactic core-collapse supernovae (CCSNe) have been suggested as potentially able to produce high-energy neutrinos.

Supernova neutrino oscillations [PDF]

open access: yesNuclear Physics B - Proceedings Supplements, 2001
We discuss some possible influence of neutrino oscillations on physics of supernova mainly focusing on the observations of $\bar _e$, and present some analysis of SN1987A data in the light of three neutrino mixing scheme.
