Global monopole in a Ricci-coupled Kalb-Ramond bumblebee gravity
F. M. Belchior, R. V. Maluf, A. Yu. Petrov +1
In this paper, we investigate black hole solutions in Einstein-Kalb-Ramond (EKR) bumblebee gravity sourced by a global monopole characterized by the charge . This modified theor…
Generalized Chern-Pontryagin models
J. R. Nascimento, A. Yu. Petrov, P. J. Porfírio +1
We formulate a new class of modified gravity models, that is, generalized four-dimensional Chern-Pontryagin models, whose action is characterized by an arbitrary function of the Ri…
Thermodynamical properties of a deformed Schwarzschild black hole via Dunkl generalization
P. Sedaghatnia, H. Hassanabadi, A. A. Araújo Filho +2
In this paper, we construct a deformed Schwarzschild black hole from the de Sitter gauge theory of gravity within Dunkl generalization and we determine the metric coefficients vers…
Gödel-type solutions within the gravity
J. R. Nascimento, A. Yu. Petrov, P. J. Porfirio +1
In this work, we scrutinize the consistency of spacetime homogeneous Gödel-type metrics within theories of gravity for well-motivated matter sources. As it is well known…
Quasinormal modes of Schwarzschild black holes in projective invariant Chern-Simons modified gravity
Simon Boudet, Flavio Bombacigno, Gonzalo J. Olmo +1
We generalize the Chern-Simons modified gravity to the metric-affine case and impose projective invariance by supplementing the Pontryagin density with homothetic curvature terms w…
First-order perturbations of Gödel-type metrics in non-dynamical Chern-Simons modified gravity
B. Altschul, J. R. Nascimento, A. Yu. Petrov +1
Gödel-type metrics that are homogeneous in both space and time remain, like the Schwarzschild metric, consistent within Chern-Simons modified gravity; this is true in both the non-…
