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…
Dirac-Bergmann analysis and Degrees of Freedom of Coincident -gravity
Kyosuke Tomonari, Sebastian Bahamonde
We investigate the propagating degrees of freedom of -gravity in a -dimensional space-time under the imposition of the coincident gauge by performing the Dirac-Bergmann an…
Distinctive Features of Hairy Black Holes in Teleparallel Gauss-Bonnet Gravity
Sebastian Bahamonde, Daniela D. Doneva, Ludovic Ducobu +2
We examine the teleparallel formulation of non-minimally coupled scalar Einstein-Gauss-Bonnet gravity. In the teleparallel formulation, gravity is described by torsion instead of c…
Algebraic classification of the gravitational field in Weyl-Cartan space-times
Sebastian Bahamonde, Jorge Gigante Valcarcel
We present a complete algebraic classification for the curvature tensor in Weyl-Cartan geometry, by applying methods of eigenvalues and principal null directions on its irreducible…
