Hubble stream near a massive object: The exact analytical solution for the spherically-symmetric case
Physical Review D ( IF 5 ) Pub Date : A. N. Baushev
Physical Review D ( IF 5 ) Pub Date : A. N. Baushev
The gravitational field of a massive object (for instance, of a galaxy group or cluster) disturbs the Hubble stream, decreasing its speed. Dependence of the radial velocity of the stream from the present-day radius can be directly observed and may provide valuable information about the cluster properties. We offer an exact analytical relationship for a spherically-symmetric system.
