Sterile dark matter and reionization
Alexander Kusenko
Sterile neutrinos with masses in the keV range can be the dark matter, and their emission from a supernova can explain the observed velocities of pulsars. The sterile neutrino deca…
Detecting sterile dark matter in space
Alexander Kusenko
Space-based instruments provide new and, in some cases, unique opportunities to search for dark matter. In particular, if dark matter comprises sterile neutrinos, the x ray detecti…
Thermal evolution of the primordial clouds in warm dark matter models with keV sterile neutrinos
Jaroslaw Stasielak, Peter L. Biermann, Alexander Kusenko
We analyze the processes relevant for star formation in a model with dark matter in the form of sterile neutrinos. Sterile neutrino decays produce an X-ray background radiation tha…
Relic keV sterile neutrinos and reionization
Peter L. Biermann, Alexander Kusenko
A sterile neutrino with mass of several keV can account for cosmological dark matter, as well as explain the observed velocities of pulsars. We show that X-rays produced by the dec…
