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…
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…
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…
Scalar geons in Born-Infeld gravity
V. I. Afonso, Gonzalo J. Olmo, D. Rubiera-Garcia
The existence of static, spherically symmetric, self-gravitating scalar field solutions in the context of Born-Infeld gravity is explored. Upon a combination of analytical approxim…
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…
