Acceleration of particles by Janis-Newman-Winicour singularities

Mandar Patil, Pankaj S. Joshi

We examine here the acceleration of particles and high energy collisions in the the Janis-Newman- Winicour (JNW) spacetime, which is an extension of the Schwarzschild geometry when…

Circular geodesics and accretion disks in Janis-Newman-Winicour and Gamma metric

Anirban N. Chowdhury, Mandar Patil, Daniele Malafarina +1

We study here circular timelike geodesics in the Janis-Newman-Winicour and Gamma metric spacetimes which contain a strong curvature naked singularity and reduce to the Schwarzschil…

Trace dynamics and a noncommutative special relativity

Kinjalk Lochan, T. P. Singh

Trace Dynamics is a classical dynamical theory of noncommuting matrices in which cyclic permutation inside a trace is used to define the derivative with respect to an operator. We…

Acceleration of particles and shells by Reissner-Nordström naked singularities

Mandar Patil, Pankaj S. Joshi, Masashi Kimura +1

We explore the Reissner-Nordström naked singularities with a charge larger than its mass from the perspective of the particle acceleration. We first consider a collision be…

Genericity aspects in gravitational collapse to black holes and naked singularities

Pankaj S. Joshi, Daniele Malafarina, Ravindra V. Saraykar

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…

Equilibrium configurations from gravitational collapse

Pankaj S. Joshi, Daniele Malafarina, Ramesh Narayan

We develop here a new procedure within Einstein's theory of gravity to generate equilibrium configurations that result as the final state of gravitational collapse from regular ini…

Instability of black hole formation under small pressure perturbations

Pankaj S. Joshi, Daniele Malafarina

We investigate here the spectrum of gravitational collapse endstates when arbitrarily small perfect fluid pressures are introduced in the classic black hole formation scenario as d…

High Energy Particle Collisions in Superspinning Kerr Geometry

Mandar Patil, Pankaj S. Joshi

We investigate here the particle acceleration and high energy collision in the Kerr geometry containing a naked singularity. We show that the center of mass energy of collision bet…

Naked Singularities as Particle Accelerators II

Mandar Patil, Pankaj S. Joshi, Daniele Malafarina

We generalize here our earlier results on particle acceleration by naked singularities. We showed recently[1] that the naked singularities that form due to gravitational collapse o…

Instability of black hole formation in gravitational collapse

Pankaj S. Joshi, Daniele Malafarina

We consider here the classic scenario given by Oppenheimer, Snyder, and Datt, for the gravitational collapse of a massive matter cloud, and examine its stability under the introduc…
