Sterile neutrinos with pseudoscalar self-interactions and cosmology
Maria Archidiacono, Steen Hannestad, Rasmus Sloth Hansen +1
Sterile neutrinos in the electronvolt mass range are hinted at by a number of terrestrial neutrino experiments. However, such neutrinos are highly incompatible with data from the C…
Self-induced flavor conversion of supernova neutrinos on small scales
Sovan Chakraborty, Rasmus Sloth Hansen, Ignacio Izaguirre +1
Self-induced flavor conversion of supernova (SN) neutrinos is a generic feature of neutrino-neutrino dispersion. The corresponding run-away modes in flavor space can spontaneously…
Active-sterile neutrino oscillations in the early Universe with full collision terms
Steen Hannestad, Rasmus Sloth Hansen, Thomas Tram +1
Sterile neutrinos are thermalised in the early Universe via oscillations with the active neutrinos for certain mixing parameters. The most detailed calculation of this thermalisati…
