Perturbations of a Schwarzschild black hole in torsion bigravity
Vasilisa Nikiforova
In this paper we pursue the study of linear perturbations around a Schwarzschild black hole in a generalized Einstein-Cartan theory of gravity, called torsion bigravity. This theor…
Spherically symmetric perturbations of a Schwarzschild black hole in torsion bigravity
Vasilisa Nikiforova
Time-dependent spherically-symmetric perturbations of Schwarzschild black holes are studied within torsion bigravity, i.e., within generalized Einstein-Cartan theories where the dy…
Black holes in the long-range limit of torsion bigravity
Vasilisa Nikiforova
We continue the study of spherically symmetric black hole solutions in torsion bigravity, a class of Einstein-Cartan-type gravity theories involving, besides a metric, a massive pr…
Black holes in torsion bigravity
Vasilisa Nikiforova, Thibault Damour
We study spherically symmetric black hole solutions in a four-parameter Einstein-Cartan-type class of theories, called "torsion bigravity". These theories offer a geometric framewo…
Absence of a Vainshtein radius in torsion bigravity
Vasilisa Nikiforova
It was pointed out long ago by Vainshtein [Phys. Lett. 39B, 393 (1972)] that the weak-field perturbation expansion of generic theories (of the nonlinear Fierz-Pauli type) involving…
Spherically symmetric solutions in torsion bigravity
Thibault Damour, Vasilisa Nikiforova
We study spherically symmetric solutions in a four-parameter Einstein-Cartan-type class of theories. These theories include torsion, as well as the metric, as dynamical fields, and…
