The nature of dark matter and galactic rotation curves
AIP conference proceedings1995Vol. 336, pp. 133–136
Abstract
It is shown that if dark matter consists of particles of masses mi, spins Ji then mi=2kT/v2m=156.9E−1/4 keV (vm is the galactic rotation velocity at large r and T is the temperature of dark matter at the galactic location, E is the emissivity of dark matter at 6450 angstroms. Relations determining the emissivity of dark matter and the flux of radiation originating in a halo of dark matter are given [Eqs. (7), (8)].
