Fast Radio Bursts as cosmological proxies: estimating the Hubble constant
Eduard Fernando Piratova-Moreno, Luz Ángela García, Carlos A. Benavides-Gallego +1
One of the most challenging problems in cosmology is the Hubble tension, a discrepancy in the predicted expansion rate of the Universe. We leverage the sensitivity of the Dispersio…
Observing the eye of the storm I: testing regular black holes with LVK and EHT observations
Carlos A. Benavides-Gallego, Swarnim Shashank, Haiguang Xu
According to the celebrated singularity theorems, space-time singularities in general relativity are inevitable. However, it is generally believed that singularities do not exist i…
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…
Gravitational waves and electromagnetic radiation from charged black hole binaries
Carlos A. Benavides-Gallego, Wen-Biao Han
It is still an open issue if astrophysical black holes have electric charges or not. In this work, we analytically calculate gravitational and electromagnetic waveforms in the freq…

In this work, we investigated the motion of spinning test particles around a rotating wormhole, extending, in this way, the previous work of Benavides-Gallego et al. in [Phys. Rev.…
Phenomenological model for the electromagnetic response of a black hole binary immersed in magnetic field
Carlos A. Benavides-Gallego, Wen-Biao Han
Electromagnetic counterparts of gravitational wave events usually involve neutron stars during compact binary coalescences. On the other hand, the community generally believes that…
Spinning test particle motion around a traversable wormhole
Carlos A. Benavides-Gallego, Wen-Biao Han, Daniele Malafarina +2
The motion of spinning test particles around a traversable wormhole is investigated using the Mathisson Papapetrous Dixon equations, which couple the Riemann tensor with the antisy…
A surrogate model for gravitational waveforms of spin-aligned binary black holes with eccentricities
Qianyun Yun, Wen-Biao Han, Xingyu Zhong +1
A waveform model for the eccentric binary black holes named SEOBNRE has been used to analyze the LIGO-Virgo's gravitational wave data by several groups. The accuracy of this model…
Quasi-harmonic oscillations of charged particles in static axially symmetric space-times immersed in a uniform magnetic field
Carlos A. Benavides-Gallego, Ahmadjon Abdujabbarov, Daniele Malafarina +1
In continuation of our previous study [Phys. Rev. D 99 (2019) 4, 044012], we investigate the motion of charged particles in the -metric. We provide some examples of curled traje…
