Pulsar kicks, dark matter, and the future observations of X-ray telescopes
Abstract
A sterile neutrino with mass in the 1--20 keV range and a small mixing with the electron neutrino can simultaneously explain the origin of the pulsar motions and the dark matter in the universe. If such a particle exists, an asymmetric emission from a hot nascent neutron star can be the explanation of the observed pulsar velocities. The same particle can be the cosmological dark matter. X-ray telescopes, such as Chandra and Constellation-X, may be able to detect keV photons from the decays of these particles in the galactic halos.
