Gravitational frequency shift of light signals in a pulsating dark matter halo

Abstract

The gravitational frequency shift of light signals from the center of a spherically symmetric non-static matter distribution is considered. Explicit formulas for the ratio of the emitted and received frequencies are obtained in the case of the oscillating scalar dark matter with logarithmic potential.
