Genericity of black holes and naked singularities in gravitational collapse
Gravitational collapse black holes naked singularity
2011/10/14
We investigate here the genericity and stability aspects for naked singularities and black holes that arise as the final states for a complete gravitational collapse of a spherical massive matter clou...
Can accretion disk properties observationally distinguish black holes from naked singularities?
accretion disk properties black holes naked singularities

Naked singularities are hypothetical astrophysical objects, characterized by a gravitational sin-gularity without an event horizon. Penrose has proposed a conjecture, according to which there exists a...

Naked singularities are hypothetical astrophysical objects, characterized by a gravitational singularity without an event horizon. Penrose has proposed a conjecture, according to which there exists a ...
We investigate here the particle acceleration by naked singularities to arbitrarily high center of mass energies. Recently it has been suggested that black holes could be used as particle accelerators...
Applications of the Tunneling Method to Particle Decay and Radiation from Naked Singularities
Particle Decay Radiation Naked Singularities

Following recent literature on dS instability in presence of interactions, we study the decay of massive particles in general FRW models and the emission from naked singularities either associated wit...
