Black hole mass and distance from accretion disk astrophysical observables
J. R. Fernández-Moreno, A. González-Juárez, A. Herrera-Aguilar
In this work we derive novel analytical expressions for the mass and distance of a Schwarzschild black hole (BH), as well as for the orbital radius of test particles orbiting it, i…
Cosmological redshift of a Schwarzschild-de Sitter black hole: Towards estimating the Hubble constant
Deborah Villaraos, Alfredo Herrera-Aguilar, Mehrab Momennia +1
In this work we estimate the parameters of several astrophysical black holes hosted at the core of active galactic nuclei by studying the kinematics of test objects in their accret…
Mass and distance of AGN black holes from warped accretion disks
Adriana González-Juárez, Alfredo Herrera-Aguilar
Along the last ten years, a general relativistic method has been developed to generate analytical expressions for the black hole (BH) parameters in terms of observables, namely the…
Testing conformal gravity using the supermassive black hole NGC 4258
Diego A. Martínez-Valera, Alfredo Herrera-Aguilar
In this paper, we perform a Bayesian statistical fit to estimate the free parameters of a nonsingular black hole in conformal gravity by employing megamaser astrophysical data of t…
Mass, charge, and distance to Reissner-Nordström black hole in terms of directly measurable quantities
Gerardo Morales-Herrera, Pablo Ortega-Ruiz, Mehrab Momennia +1
In this paper, we employ a general relativistic formalism and develop new theoretical tools that allow us to analytically express the mass and electric charge of the Reissner-Nords…
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…
