Nonradial oscillations of realistic anisotropic neutron stars: Axial modes
Jose F. Rodriguez-Ruiz, L. M. Becerra, F. D. Lora-Clavijo
Non-radial oscillation modes of neutron stars serve as diagnostics of their internal composition and relativistic structure. In this work, we investigate the perturbations of stati…
Stable colored black holes with quartic self-interactions
Jose F. Rodriguez-Ruiz, Gabriel Gomez
We analytically prove the linear radial stability of non-Abelian black holes with quartic self-interactions. The background, constructed from the Wu-Yang magnetic monopole ansatz,…
Discrimination of metric theories
F. J. Lobo, M. Rivera-Tapia, G. Rubilar +2
We study the possibility of discriminating between metric theories within the Parametrized Post-Newtonian formalism. In this approach, the two-dimensional quantum state of a massiv…
Internal symmetry to the rescue: well-posed 1+1 evolution of self-interacting vector fields
Gabriel Gomez, Jose F. Rodriguez
Previous studies have identified potential instabilities in self-interacting vector theories associated with the breakdown of the well-posedness of the initial-value problem. Howev…
Dynamical Shortcomings in the Generalized SU(2) Proca Theory: Challenges for Cosmic Acceleration
Santiago Garcia-Serna, J. Bayron Orjuela-Quintana, Yeinzon Rodriguez +2
The Generalized SU(2) Proca (GSU2P) theory has recently garnered attention for its potential to describe key phases of cosmic evolution, including primordial inflation and late-tim…
Neutron stars in the generalized SU(2) Proca theory
Jhan N. Martinez, Jose F. Rodriguez, Laura M. Becerra +2
The generalized SU(2) Proca theory is a vector-tensor modified gravity theory characterized by an action that remains invariant under both diffeomorphisms and global internal trans…
