A Nonsingular Brans Wormhole: An Analogue to Naked Black Holes
Nonsingular Brans Wormhole Black Holes Analogue

Abstract: In a recent paper, we showed the Jordan frame vacuum Brans Class I solution provided a wormhole analogue to Horowitz-Ross naked black hole in the wormhole range -3/2<{\omega}<-4/3. Thereafte...

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...

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...

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...

Late into the evening of 8 November 1895 Wilhelm Conrad Röntgen, a physics professor at the University of Würzburg, made a discovery that would revolutionize science almost overnight. While condu...
