Playing with lepton asymmetry at the resonant production of sterile neutrino dark matter
Dmitry Gorbunov, Dmitry Kalashnikov, George Krugan
We examine the sterile neutrino dark matter production in the primordial plasma with lepton asymmetry unequally distributed over different neutrino flavors. We argue that with the…

Refining lower bounds on sterile neutrino dark matter mass from estimates of phase space densities in dwarf galaxies
Fedor Bezrukov, Dmitry Gorbunov, Ekaterina Koreshkova
Dwarf spheroidal galaxies (dSphs) are recognized as being highly dominated by Dark Matter (DM), making them excellent targets for testing DM models through astrophysical observatio…
