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…
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…
General relativistic corrections to -body simulations and the Zel'dovich approximation
Christian Fidler, Cornelius Rampf, Thomas Tram +3
The initial conditions for Newtonian -body simulations are usually generated by applying the Zel'dovich approximation to the initial displacements of the particles using an init…
