Black hole superradiance in Poincaré gauge theory
Sebastian Bahamonde, Jorge Gigante Valcarcel
We investigate the phenomenon of black hole superradiance in the presence of torsion within the framework of Poincaré gauge theory. In particular, in contrast to the classical appr…
An exact five dimensional Weyl-Geometry Gauss-Bonnet Black Hole
Sebastian Bahamonde, Máximo Bañados
We present a new exact black hole solution of a 5-dimensional Weyl-geometry Gauss-Bonnet theory of gravity. The Euclidean sector defines a fully regular metric coupled to the Weyl…
Spherically symmetric vacuum solutions in 1-Parameter New General Relativity and their phenomenology
Helen Asuküla, Sebastian Bahamonde, Manuel Hohmann +3
In this work, we study spherically symmetric vacuum solutions in 1-parameter New General Relativity (NGR), a specific theory in teleparallel gravity which is constructed from the t…
Cosmological Perturbation Theory in Metric-Affine Gravity
Katsuki Aoki, Sebastian Bahamonde, Jorge Gigante Valcarcel +1
We formulate cosmological perturbation theory around the spatially curved FLRW background in the context of metric-affine gauge theory of gravity which includes torsion and nonmetr…
Kerr-Newman Black Holes in Weyl-Cartan Theory: Shadows and EHT constraints
Khadije Jafarzade, Seyed Hossein Hendi, Mubasher Jamil +1
With the recent release of the black hole image of Sgr A* alongside the earlier image of M87*, one can achieve an in-depth understanding of gravitational physics at the horizon sca…
Symmetric Teleparallel Gauss-Bonnet Gravity and its Extensions
Juan Manuel Armaleo, Sebastian Bahamonde, Georg Trenkler +1
General Teleparallel theories assume that curvature is vanishing in which case gravity can be solely represented by torsion and/or nonmetricity. Using differential form language, w…
