Schwarzschild black hole and redshift rapidity: A new approach towards measuring cosmic distances
Mehrab Momennia, Pritam Banerjee, Alfredo Herrera-Aguilar +1
Motivated by recent achievements of a full general relativistic method in estimating the mass-to-distance ratio of supermassive black holes hosted at the core of active galactic nu…
Observational redshift from general spherically symmetric black holes
Diego A. Martinez-Valera, Mehrab Momennia, Alfredo Herrera-Aguilar
In this work, we obtain an expression for the total observational frequency shift of photons emitted by massive geodesic particles circularly orbiting a black hole in a general sph…
Kerr black hole in de Sitter spacetime and observational redshift: Toward a new method to measure the Hubble constant
Mehrab Momennia, Alfredo Herrera-Aguilar, Ulises Nucamendi
We extract the Hubble law by the frequency-shift considerations of test particles revolving the Kerr black hole in asymptotically de Sitter spacetime. To this end, we take into acc…
