Geometrothermodynamics of Black Hole Shadows: A Review
Hernando Quevedo, Jose M. Ladino, Carlos E. Romero-Figueroa +1
Black-hole shadows and geometrothermodynamics (GTD) are defined in different spaces but depend on the same macroscopic black-hole parameters. We review their correspondence for Rei…
Naked Singularities and Black Hole Thermodynamics from Shadows and Photon Rings in the Quantum Oppenheimer-Snyder Model
Jose Miguel Ladino, Anuar Idrissov, Carlos E. Romero-Figueroa +1
We investigate the optical and thermodynamic properties of quantum Oppenheimer-Snyder (qOS) spacetimes in both the black hole and naked singularity regimes. By analyzing test-parti…
Geometric Universality and Thermodynamic Microstructure of Real Fluids in a Unified Entropic Framework
Carlos E. Romero-Figueroa, Jose Miguel Ladino, Sasha A. Zaldivar +1
We introduce a unified entropic framework for real fluids that encompasses the van der Waals, Berthelot, Redlich Kwong, and Peng Robinson equations of state within a common thermod…
Probing Black Hole Thermodynamics and Microstructure via the Shadow of Sagittarius A*
Jose Miguel Ladino, Carlos E. Romero-Figueroa, Hernando Quevedo
We explore the connection between black hole shadows, thermodynamic phase structure, and microstructure of charged and rotating black holes within General Relativity and Geometroth…
Phase Transitions, Shadows, and Microstructure of Kerr-anti-de Sitter Black Holes from Geometrothermodynamics
Jose Miguel Ladino, Carlos E. Romero-Figueroa, Hernando Quevedo
Using the formalism of geometrothermodynamics, we investigate the phase-transition structure and microstructure of the Kerr-anti-de Sitter black hole and show the relationship with…
Phase transitions, shadows, and microstructure of Reissner-Nordström-Anti-de-Sitter black holes from a geometrothermodynamic perspective
Jose M. Ladino, Carlos E. Romero-Figueroa, Hernando Quevedo
We study the thermodynamic properties of the Reissner-Nordström black hole with cosmological constant, expressed in terms of the curvature radius, by using the approach of shadow t…
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…
Implementación computacional para el estudio de partículas con espín en agujeros negros rotantes modificados cuánticamente
Jose Miguel Ladino, Eduard Larrañaga
The trajectories of test particles with spin orbiting a black hole depend on the geometry of space-time and the intrinsic physical characteristics of the test particles. In this wo…
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…
