Abstract:
In this work we investigate the motion of free particle in the field of
strongly gravitating object which is embedded into dust cosmological
background. We use newly obtained exact solution of Einstein equations
in comoving coordinates for the system under consideration in case of
zero spatial curvature. Observable velocity of the particle moving
relatively to the observer comoving with cosmological expansion is found
from geodesic equations.
