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…
A differential-geometry approach to black hole characterization of megamaser systems in static spherically symmetric spacetimes
Santiago González-Salud, Rodrigo Bárcena-Ramos, Alfredo Herrera-Aguilar +1
We develop a geometry-first model that maps measured thin-disk water megamaser observables--sky angles, frequency shifts, their secular drifts and the angular redshift rate--to the…
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…
Noncommutative AdS black hole and the IR holographic superconductor
Manuel de la Cruz-López, Alfredo Herrera-Aguilar, Daniel Martínez-Carbajal +1
We construct a noncommutative (NC) AdS-charged black hole with a planar horizon topology. The NC effects of this geometry are captured by a Gaussian distribution of black hole…
