Regular charged black holes, energy conditions and quasinormal modes
Leonardo Balart, Grigoris Panotopoulos, Ángel Rincón
We discuss energy conditions and quasinormal modes for scalar perturbations of regular charged black holes within the framework of General Relativity coupled to non-linear electrod…
A Generalized Double Chaplygin Model for Anisotropic Matter: The Newtonian Case
Gabriel Abellán, Angel Rincon, Eduard Sanchez
In this work, we investigate astrophysical systems in a Newtonian regime using anisotropic matter. For this purpose, we considered that both radial and tangential pressures satisfy…
Quasinormal modes and shadow in Einstein Maxwell power-Yang-Mills black hole
Angel Rincon, Gabriel Gómez
In the present paper, we investigate the quasinormal modes of an Einstein-Maxwell power-Yang-Mills black hole in four dimensions, considering a specific value of the power paramete…
Exploring Models of Running Vacuum Energy with Viscous Dark Matter from a Dynamical System Perspective
Norman Cruz, Gabriel Gomez, Esteban Gonzalez +2
Running vacuum models and viscous dark matter scenarios beyond perfect fluid idealization are two appealing theoretical strategies that have been separately studied as alternatives…
Novel charged black hole solutions of Born-Infeld type: General properties, Smarr formula and Quasinormal frequencies
L. Balart, S. Belmar-Herrera, G. Panotopoulos +1
We investigate two novel models of charged black holes in the framework of non-linear electrodynamics of Born-Infeld type. In particular, starting from two concrete Lagrangian dens…
4D scale-dependent Schwarzschild-AdS/dS black holes: study of shadow and weak deflection angle and greybody bounding
Ali Övgün, Reggie C. Pantig, Ángel Rincón
We investigate the shadow, deflection angle, and the greybody bounding of a Schwarzschild-AdS/dS black hole in scale-dependent gravity. We used the EHT data to constrain the parame…
