The Image of Scalar Hairy Black Holes with Asymmetric Potential
Carlos A. Benavides-Gallego, Eduard Larrañaga
Black hole accretion disks are a fascinating topic in astrophysics, as they play a crucial role in several high-energy situations. This paper investigates the optical appearance of…
Comparing spin supplementary conditions for particle motion around traversable wormholes
Carlos A. Benavides-Gallego, Jose Miguel Ladino, Eduard Larrañaga
The Mathisson-Papapetrou-Dixon (MPD) equations describe the motion of spinning test particles. It is well-known that these equations, which couple the Riemann curvature tensor with…
Charged spinning and magnetized test particles orbiting quantum improved charged black holes
Jose Miguel Ladino, Carlos A. Benavides-Gallego, Eduard Larrañaga +2
In the present work, we aimed to investigate the dynamics of spinning charged and magnetized test particles around both electrically and magnetically charged quantum-improved black…
Eikonal quasinormal modes, photon sphere and shadow of a charged black hole in the 4D Einstein-Gauss-Bonnet gravity
Jose Miguel Ladino, Eduard Larrañaga
In this work, we investigate the relationship between the geometrical properties, the photon sphere, the shadow, and the eikonal quasinormal modes of electrically charged black hol…
Motion of Spinning Particles around Black Holes
Jose Miguel Ladino, Carlos Andrés del Valle, Eduard Larrañaga
The motion of spinning particles around compact objects, for example a rotating stellar object moving around a supermassive black hole, is described by differential equations that…
Motion of a spinning particle around an improved rotating black hole
Jose Miguel Ladino, Eduard Larrañaga
Using the Mathisson-Papapetrou-Dixon equations together with the Tulczyjew spin-supplementary condition, we study the circular orbits of a spinning test particle moving in the equa…
On the properties of a Static and a Stationary Charged Black Hole in Gravity
Carlos Conde, Cristian Galvis, Eduard Larrañaga
In a recent paper, Nashed and Capozziello presented a new class of charged, spherically symmetric black hole solutions of gravity with an asymptotic flat or (anti-)de Sitter…
Properties of the Innermost Stable Circular Orbit of a spinning particle moving in a rotating Maxwell-dilaton black hole background
Carlos Conde, Cristian Galvis, Eduard Larrañaga
In this paper we investigate the innermost stable circular orbit (ISCO) of a spinning test particle moving in the rotating Maxwell-dilaton black hole spacetime. By using the Mathis…
