Flowing along the edge: Spinning up black holes in AdS spacetimes with test particles

- Jorge V. Rocha, R. Santarelli
- Physics
- 19 February 2014

We investigate the consequences of throwing point particles into odd-dimensional Myers-Perry black holes in asymptotically anti-de Sitter (AdS) backgrounds. We restrict our attention to the case in… Expand

Collapsing rotating shells in Myers-Perry-AdS 5 spacetime: A perturbative approach

- Jorge V. Rocha, R. Santarelli, T. Delsate
- Physics
- 17 February 2014

We study gravitational perturbations sourced by a rotating test shell collapsing into five-dimensional Myers-Perry black holes in anti-de Sitter (AdS). Our attention is restricted to the case in… Expand

Destroying a near-extremal Kerr-Newman black hole

- A. Saa, R. Santarelli
- Physics
- 19 May 2011

We revisit here a previous argument due to Wald showing the impossibility of turning an extremal Kerr-Newman black hole into a naked singularity by plunging test particles across the black hole event… Expand

Geodesic motion in equal angular momenta Myers-Perry-AdS spacetimes

- T. Delsate, Jorge V. Rocha, R. Santarelli
- Physics
- 13 July 2015

nd that the ISCO dives below the ergosurface for black holes rotating close to extremality and merges with the event horizon exactly at extremality, in analogy with the fourdimensional Kerr case. For… Expand

Scanning the parameter space of collapsing rotating thin shells

- Jorge V. Rocha, R. Santarelli
- Physics
- 20 November 2017

We present results of a comprehensive study of collapsing and bouncing thin shells with rotation, framing it in the context of the weak cosmic censorship conjecture. The analysis is based on a… Expand

Gravitational collapse with rotating thin shells and cosmic censorship

- T. Delsate, Jorge V. Rocha, R. Santarelli
- Physics
- 28 April 2015

The study of gravitational collapse is a subject of great importance, both from an astrophysical and a holographic point of view. In this respect, exact solutions can be very helpful but known… Expand

Mass evolution of Schwarzschild black holes.

- N. D. Santi, R. Santarelli
- Physics
- 17 June 2019

In the classical theory of general relativity black holes can only absorb and not emit particles. When quantum mechanical effects are taken into account, then the black holes emit particles as hot… Expand

Collapsing thin shells with rotation

- T. Delsate, Jorge V. Rocha, R. Santarelli
- Physics
- 6 May 2014

We construct exact solutions describing the motion of rotating thin shells in a fully backreacted five-dimensional rotating black hole spacetime. The radial equation of motion follows from the… Expand
