Testing the QGP Star Hypothesis: The oMEGACat BH-2 System as a Candidate Color-Superconducting Quark-Gluon Plasma Star
Herman J. Mosquera Cuesta
The recent discovery of a long-period binary system in the globular cluster Centauri, oMEGACat BH-2 \citep{Whitaker2026}, provides an unprecedented opportunity to probe the tru…
Probing nonlinear electrodynamics in slowly rotating spacetimes through neutrino astrophysics
Herman J. Mosquera Cuesta, Gaetano Lambiase, Jonas P. Pereira
Huge electromagnetic fields are known to be present during the late stages of the dynamics of supernovae. Thus, when dealing with electrodynamics in this context, the possibility m…
Farewell to black hole horizons and singularities?
C. Corda, D. Leiter, H. J. Mosquera Cuesta +2
We consider the fundamental issues which dominate the question about the existence or non-existence of black hole horizons and singularities from both of the theoretical and observ…
Irreversible gravitational collapse: black stars or black holes?
Christian Corda, Herman J. Mosquera Cuesta
It is well known that the concept of black hole has been considered very fascinating by scientists even before the introduction of Einstein's general relativity. They should be the…
High-energy scalarons in R^{2} gravity as a model for Dark Matter in galaxies
Christian Corda, Herman J. Mosquera Cuesta, Roberto Lorduy Gòmez
We show that in the framework of R^{2} gravity and in the linearized approach it is possible to obtain spherically symmetric stationary states that can be used as a model for galax…
Removing black-hole singularities with nonlinear electrodynamics
Christian Corda, Herman J. Mosquera Cuesta
We propose a way to remove black hole singularities by using a particular nonlinear electrodynamics Lagrangian that has been recently used in various astrophysics and cosmological…
Confronting the Hubble Diagram of Gamma-Ray Bursts with Cardassian Cosmology
Herman J. Mosquera Cuesta, Habib Dumet M., Cristina Furlanetto
We construct the Hubble diagram (HD) of Gamma-Ray Bursts (GRBs) with redshifts reaching up to , by using five luminosity vs. luminosity indicator relations calibrated wit…
Supermassive screwed cosmic string in dilaton gravity
Valdir B. Bezerra, Cristine N. Ferreira, Herman J. Mosquera Cuesta
The early Universe might have undergone phase transitions at energy scales much higher than the one corresponding to the Grand Unified Theories (GUT) scales. At these higher energy…
Quark stars and quantum-magnetically induced collapse
A. Perez Martinez, H. Perez Rojas, H. J. Mosquera Cuesta +2
Quark matter is expected to exist in the interior of compact stellar objects as neutron stars or even the more exotic strange stars, based on the Bodmer-Witten conjecture. Bare str…
An origin for the main pulsation and overtones of SGR1900+14 during the August 27 (1998) superoutburst
Herman J. Mosquera Cuesta
The crucial observation on the occurrence of subpulses (overtones) in the Power Spectral Density of the August 27 (1998) event from SGR1900+14, as discovered by BeppoSAX (Feroci et…
A white dwarf-neutron star relativistic binary model for soft gamma-ray repeaters
Herman J. Mosquera Cuesta
A scenario for SGRs is introduced in which gravitational radiation reaction effects drive the dynamics of an ultrashort orbital period X-ray binary embracing a high-mass donor whit…
Observational evidence of spin-induced precession in active galactic nuclei
Anderson Caproni, Herman J. Mosquera Cuesta, Zulema Abraham
We show that it is possible to explain the physical origin of jet precession in active galactic nuclei (AGNs) through the misalignment between the rotation axes of the accretion di…
Einstein's gravitational lensing and nonlinear electrodynamics
Herman J. Mosquera Cuesta, Jose' A. de Freitas Pacheco, Jose' M. Salim
In 1936 Einstein predicted the phenomenon presently known as gravitational lensing (GL). A prime feature of GL is the magnification, because of the gravitational field, of the star…
Powerful gravitational-wave bursts from supernova neutrino oscillations
Herman J. Mosquera Cuesta, Karen Fiuza
During supernova core collapse and bounce resonant active-to-active, as well as active-to-sterile, neutrino () oscillations can take place. Over this phase weak magnetism increa…

Herman J. Mosquera Cuesta, Karen Fiuza
During the core bounce of a supernova collapse resonant active-to-active (), as well as active-to-sterile () neutrino () oscillations can take place. B…
Exploding Bose-Einstein condensates and collapsing neutron stars driven by critical magnetic fields
H. Pérez Rojas, A. Pérez Martínez, H. J. Mosquera Cuesta
The problem of a condensate of a relativistic neutral vector boson gas constituted of particles bearing a magnetic moment is discussed. Such a vector boson system is expected to be…
Nonlinear electrodynamics and the gravitational redshift of highly magnetised neutron stars
Herman J. Mosquera Cuesta, Jose' M. Salim
The idea that the nonlinear electromagnetic interaction, i. e., light propagation in vacuum, can be geometrized was developed by Novello et al. (2000) and Novello & Salim (2001). S…
Cosmic optical activity in the spacetime of a scalar-tensor screwed cosmic string
V. B. Bezerra, H. J. Mosquera Cuesta, C. N. Ferreira
Measurements of radio emission from distant galaxies and quasars verify that the polarization vectors of these radiations are not randomly oriented as naturally expected. This pecu…
Quantum instability of magnetized stellar objects
R. Gonzalez Felipe, H. J. Mosquera Cuesta, A. Perez Martinez +1
The equations of state for degenerate electron and neutron gases are studied in the presence of magnetic fields. After including quantum effects to study the structural properties…
Charge Asymmetry in the Brane World and Formation of Charged Black Holes
Herman J. Mosquera Cuesta, André Penna-Firme, Abdel Pérez-Lorenzana
In theories with an infinite extra dimension, free particles localized on the brane can leak out to the extra space. We argue that if there were color confinement in the bulk, elec…

Gravitational-wave bursts from soft gamma-ray repeaters: Can they be detected?
H. J. Mosquera Cuesta, J. C. N. de Araujo, O. D. Aguiar +1
In this letter we suggest a scenario for simultaneous emission of gravitational-wave and -ray bursts (GRBs) from soft gamma-ray repeaters (SGRs). we argue that both of the radia…
