Asymptotically AdS black hole with a conformally-coupled scalar field in the first-order formalism of gravity
L. Avilés, C. Corral, F. Izaurieta +2
We present a novel asymptotically anti-de Sitter black hole solution with conformally-coupled scalar fields in the first-order formalism of gravity in four dimensions. To do so, we…
Thermodynamics of the three-dimensional black hole with torsion
Luis Avilés, Diego Hidalgo, Omar Valdivia
The stationary black hole solution of a Chern-Simons model based on the semi-simple extension of the Poincaré gauge group is studied. The solution resembles the metric properties o…
Mimetic Einstein-Cartan-Kibble-Sciama (ECKS) gravity
F. Izaurieta, P. Medina, N. Merino +2
In this paper, we formulate the Mimetic theory of gravity in first-order formalism for differential forms, i.e., the mimetic version of Einstein-Cartan-Kibble-Sciama (ECKS) gravity…
The Spin Tensor of Dark Matter and the Hubble Parameter Tension
Fernando Izaurieta, Samuel Lepe, Omar Valdivia
Allowing for a nonvanishing spin tensor for cold dark matter () has the consequence of giving rise to an effective dynamics with a small negative…
Luminal Propagation of Gravitational Waves in Scalar-tensor Theories: The Case for Torsion
José Barrientos, Fabrizio Cordonier-Tello, Cristóbal Corral +4
Scalar-tensor gravity theories with a nonminimal Gauss-Bonnet coupling typically lead to an anomalous propagation speed for gravitational waves, and have therefore been tightly con…
Wave Operators, Torsion, and Weitzenböck Identities
José Barrientos, Fernando Izaurieta, Eduardo Rodríguez +1
We offer a mathematical toolkit for the study of waves propagating on a background manifold with nonvanishing torsion. Examples include electromagnetic and gravitational waves on a…
Linear and Second-order Geometry Perturbations on Spacetimes with Torsion
Fernando Izaurieta, Eduardo Rodríguez, Omar Valdivia
In order to study gravitational waves in any realistic astrophysical scenario, one must consider geometry perturbations up to second order. Here, we present a general technique for…
Nonminimal couplings, gravitational waves, and torsion in Horndeski's theory
José Barrientos, Fabrizio Cordonier-Tello, Fernando Izaurieta +4
The Horndeski Lagrangian brings together all possible interactions between gravity and a scalar field that yield second-order field equations in four-dimensional spacetime. As orig…
A generalized action for -dimensional Chern--Simons gravity
José Díaz, Octavio Fierro, Fernando Izaurieta +4
We show that the so-called semi-simple extended Poincaré (SSEP) algebra in dimensions can be obtained from the anti-de~Sitter algebra by me…
