TL;DR
This paper derives formulas for the gravitational frequency shift of light signals in a pulsating dark matter halo, focusing on scalar dark matter with a logarithmic potential, to understand how oscillations affect light frequency.
Contribution
It provides explicit formulas for frequency shifts in a non-static, spherically symmetric dark matter distribution with oscillating scalar fields, a novel analysis for such systems.

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.
