Accelerated observers and the notion of singular spacetime
Gonzalo J. Olmo, Diego Rubiera-Garcia, Antonio Sanchez-Puente
Geodesic completeness is typically regarded as a basic criterion to determine whether a given spacetime is regular or singular. However, the principle of general covariance does no…
Nonsingular black holes, wormholes, and de Sitter cores from anisotropic fluids
C. Menchon, Gonzalo J. Olmo, D. Rubiera-Garcia
We study Born-Infeld gravity coupled to an anisotropic fluid in a static, spherically symmetric background. The free function characterizing the fluid is selected on the following…
Observable traces of non-metricity: new constraints on metric-affine gravity
A. Delhom I Latorre, Gonzalo J. Olmo, Michele Ronco
Relaxing the Riemannian condition to incorporate geometric quantities such as torsion and non-metricity may allow to explore new physics associated with defects in a hypothetical s…
On gravitational waves in Born-Infeld inspired non-singular cosmologies
Jose Beltran Jimenez, Lavinia Heisenberg, Gonzalo J. Olmo +1
We study the evolution of gravitational waves for non-singular cosmological solutions within the framework of Born-Infeld inspired gravity theories, with special emphasis on the Ed…
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…
Born-Infeld inspired modifications of gravity
Jose Beltran Jimenez, Lavinia Heisenberg, Gonzalo J. Olmo +1
General Relativity has shown an outstanding observational success in the scales where it has been directly tested. However, modifications have been intensively explored in the regi…
