Enhancement or damping of fast neutrino flavor conversions due to collisions
Rasmus S. L. Hansen, Shashank Shalgar, Irene Tamborra
Fast neutrino flavor conversion can occur in core-collapse supernovae or compact binary merger remnants when non-forward collisions are also at play, and neutrinos are not fully de…
Triangulating Black Hole Forming Stellar Collapses through Neutrinos
Lila Sarfati, Rasmus S. L. Hansen, Irene Tamborra
In the event of a black hole (BH) forming stellar collapse, the neutrino signal should terminate abruptly at the moment of BH formation, after a phase of steady accretion. Since ne…
Neutrino flavor mixing breaks isotropy in the early universe
Rasmus S. L. Hansen, Shashank Shalgar, Irene Tamborra
The neutrino field is commonly assumed to be isotropic and homogeneous in the early universe. However, due to the large neutrino density, a small perturbation of the isotropy of th…
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…
