Decays and annihilation of galactic dark matter: determine $D$ -, $J_{s}$ -, $J_{p}$ - and $J_{d}$ -factors with dark matter profiles inferred from GravSphere fit to stellar observations

Fedor Bezrukov, Dmitry Gorbunov, Ekaterina Koreshkova

Dark matter mass density profiles and velocity distributions for a set of dwarf spheroidal galaxies (dSphs) have recently been obtained (F.Bezrukov, D.Gorbunov, E.Koreshkova arXiv:…

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…
