ABSTRACT:
The effect of light refraction
in a galaxy’s halo of dark matter, described by profiles of Navarro-Frenk-White
and Burkert, was considered. Powers of the Cherenkov radiation for the refractive
indexes of gravitational fields with these profiles were calculated. It was
shown that correspondent radiation temperature in the X-rays diapason have the
magnitude about T~10-6K . It was
also marked that its detection may be the criteria on choosing the preferable
dark matter density distribution in a galaxy.
