Disks in Expanding FRW Universes
/ Authors
/ Abstract
We construct exact solutions to Einstein equations representing relativistic disks embedded in an expanding FRW universe. We show that the expansion influences kinematical characteristics of the disks, such as rotational curves, surface mass density, etc. The effects of the expansion are exemplified with nonstatic generalizations of Kuzmin-Curzon and Schwarzschild disks.
