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…
