MeV-scale reheating temperature and cosmological production of light sterile neutrinos
Takuya Hasegawa, Nagisa Hiroshima, Kazunori Kohri +3
We investigate how sterile neutrinos with a range of masses influence cosmology in MeV-scale reheating temperature scenarios. By computing the production of sterile neutrinos throu…
MeV-scale reheating temperature and thermalization of oscillating neutrinos by radiative and hadronic decays of massive particles
Takuya Hasegawa, Nagisa Hiroshima, Kazunori Kohri +3
From a theoretical point of view, there is a strong motivation to consider an MeV-scale reheating temperature induced by long-lived massive particles with masses around the weak sc…
Stability of three neutrino flavor conversion in supernovae
Christian Döring, Rasmus S. L. Hansen, Manfred Lindner
Neutrino-neutrino interactions can lead to collective flavor conversion in the dense parts of a core collapse supernova. Growing instabilities that lead to collective conversions h…
Effect of extended neutrino production region on collective oscillations in supernovae
Rasmus S. L. Hansen, Alexei Yu. Smirnov
In supernovae neutrinos are emitted from a region with a width of a few kilometers (rather than from a surface of infinitesimal width). We study the effect of integra…
IceCube Flavor Ratios with Identified Astrophysical Sources: Towards Improving New Physics Testability
Vedran Brdar, Rasmus S. L. Hansen
Motivated by the discovery of the first high-energy astrophysical neutrino source, the blazar TXS 0506+056, we revisit the IceCube flavor ratio analysis. Assuming large statistics…
Thermalizing sterile neutrino dark matter
Rasmus S. L. Hansen, Stefan Vogl
Sterile neutrinos produced through oscillations are a well motivated dark matter candidate, but recent constraints from observations have ruled out most of the parameter space. We…
