Does supernova feedback regulate the star formation rate in dwarf galaxies?
D. Whitworth, E. Vázquez-Semadeni, J. Ballesteros-Paredes +1
Stars form in cold, dense clouds embedded in galactic discs, but whether their formation is primarily regulated by gravitational collapse, turbulence, or stellar feedback remains u…
Gravitational wave oscillations in Multi-Proca dark energy models
Gabriel Gomez, Jose F. Rodriguez
Gravitational wave oscillations arise from the exchange of energy between the metric perturbations and additional tensor modes. This phenomenon can occur even when the extra degree…
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…
Scalar Field Dark Matter Around Charged Black Holes
Yuri Ravanal, Gabriel Gómez, Norman Cruz
In this paper, we investigate the behavior of a massive scalar field dark matter scenarios in the large mass limit around a central Reissner-Nordström black hole. This study is mot…
Constraining Self-interacting Scalar Field Dark Matter From the Black Hole Shadow of the Event Horizon Telescope
Gabriel Gómez, Patrick Valageas
An exciting possibility to constrain dark matter (DM) scenarios is to search for their gravitational imprints on Black Hole (BH) observations. In this paper, we investigate the imp…
Particle-like solutions in the generalized SU(2) Proca theory
Jhan N. Martinez, Jose F. Rodriguez, Yeinzon Rodriguez +1
The generalized SU(2) Proca theory is a vector-tensor modified gravity theory where the action is invariant under both diffeomorphisms and global internal transformations of the SU…
