Gravitational frequency shift of light signals in a pulsating dark matter halo
Vladimir A. Koutvitsky, Eugene M. Maslov
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 e…

Deflection of light in time-periodic spherically symmetric gravitational fields
Vladimir A. Koutvitsky, Eugene M. Maslov
Using the geodesic method and the perturbative approach, we study the deflection of light by time-periodic spherically symmetric gravitational fields. Assuming the weakness of the…

Analytical study of the parametric instability of an oscillating scalar field in an expanding universe
Vladimir A. Koutvitsky, Eugene M. Maslov
We investigate the dynamics of the perturbations of the inflaton scalar field oscillating around a minimum of its effective potential in an expanding universe. With the assumption…
