Resonant phenomena in finite motions of test particles in oscillating dark matter configurations
Vladimir A. Koutvitsky, Eugene M. Maslov
Nonlinear differential equations are derived that describe the time evolution of the test particle coordinates during finite motions in the gravitational field of oscillating dark…
Passage of test particles through oscillating spherically-symmetric dark matter configurations
Vladimir A. Koutvitsky, Eugene M. Maslov
Applying the perturbative approach to geodesic equations, we study motion of the test particles in time-dependent spherically symmetric spacetimes created by oscillating dark matte…
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…
On the oscillation-driven cosmological expansion at the post-inflation stage
Vladimir A. Koutvitsky, Eugene M. Maslov
Dynamics of the inflaton scalar field oscillating around a minimum of the singular potentials in the expanding Universe is investigated. Asymptotic formulas are obtained describing…
