Relaxation of a Vlasov gas to an inhomogeneous state due to phase space mixing in an axisymmetric potential: A Newtonian analogy of the Kerr orbital motion
Ana Laura García-Perciante, Ana Laura Garc\a'ia-Perciante, Merce Guerrero +3
We explore the dynamics of a Vlasov gas propagating in an external axisymmetric potential consisting of a central potential with an additional quadrupolar component which gives ris…
Geodesic completeness of effective null geodesics in regular space-times with non-linear electrodynamics
Merce Guerrero, Gonzalo J. Olmo, Diego Rubiera-Garcia
We study the completeness of light trajectories in certain spherically symmetric regular geometries found in Palatini theories of gravity threaded by non-linear (electromagnetic) f…
Multi-ring images of thin accretion disk of a regular naked compact object
Merce Guerrero, Gonzalo J. Olmo, Diego Rubiera-Garcia +1
We discuss the importance of multi-ring images in the optical appearance of a horizonless spherically symmetric compact object, when illuminated by an optically thin accretion disk…
Light ring images of double photon spheres in black hole and wormhole space-times
Merce Guerrero, Gonzalo J. Olmo, Diego Rubiera-Garcia +1
The silhouette of a black hole having a critical curve (an unstable bound photon orbit) when illuminated by an optically thin accretion disk whose emission is confined to the equat…
Pre-main sequence evolution of low-mass stars in Eddington-inspired Born-Infeld gravity
Merce Guerrero, Diego Rubiera-Garcia, Aneta Wojnar
We study three aspects of the early-evolutionary phases in low-mass stars within Eddington-inspired Born-Infeld (EiBI) gravity, a viable extension of General Relativity. These aspe…
Charged BTZ-type solutions in Eddington-inspired Born-Infeld gravity
Merce Guerrero, Gerardo Mora-Pérez, Gonzalo J. Olmo +2
We construct an axially symmetric solution of Eddington-inspired Born-Infeld gravity coupled to an electromagnetic field in 2+1 dimensions including a (negative) cosmological const…
