McVittie solution in f(T) gravity
Cecilia Bejarano, Rafael Ferraro, María José Guzmán
We show that McVittie geometry, which describes a black hole embedded in a FLRW universe, not only solves Einstein equations but also remains as a non-deformable solution of f(T) g…
The role of torsion in projective invariant theories of gravity with non-minimally coupled matter fields
V. I. Afonso, Cecilia Bejarano, Jose Beltran Jimenez +2
We study a large family of metric-affine theories with a projective symmetry, including non-minimally coupled matter fields which respect this invariance. The symmetry is straightf…
What is a singular black hole beyond General Relativity?
Cecilia Bejarano, Gonzalo J. Olmo, Diego Rubiera-Garcia
Exploring the characterization of singular black hole spacetimes, we study the relation between energy density, curvature invariants, and geodesic completeness using a quadratic $f…
