Black Hole Shadow Drift and Photon Ring Frequency Drift
The apparent angular size of the shadow of a black hole in an expanding Universe is redshift-dependent. Since cosmological redshifts change with time - known as the redshift drift - all redshift-dependent quantities acquire a time dependence, and _a fortiori_ so do black hole shadows. We find a math...
