Can Light Cross a Singularity? Exact Solutions from Analogue Gravity
Juan Manuel Paez, Franco Fiorini, Santiago M. Hernández
Using a simple spacetime hosting a strong curvature naked singularity, we employ an analogue gravity model to study electromagnetic fields in this background. We find exact solutio…
Shadows cast by a class of rotating black bounces with an anisotropic fluid
Ernesto F. Eiroa, Juan M. Paez
In this work, we introduce a family of rotating black bounces with an anisotropic fluid obtained by using a modified Newman-Janis algorithm. We analyze the main features of these s…
Shedding Light on Naked Singularities
Franco Fiorini, Santiago Hernandez, Juan Manuel Paez
Electromagnetic waves propagating in the background provided by a spacetime hosting a strong curvature, naked singularity, are fully studied. The analysis is performed not only in…
Exact results in a punctured neighborhood of a strong curvature singularity
Franco Fiorini, Juan Manuel Paez
By constructing a model of spacetime having a strong curvature singularity in which causal geodesics are complete, but more generic causal curves are not, we explicitly show that s…
