The Evolution of Distorted Rotating Black Holes III: Initial Data [PDF]
, 1996 In this paper we study a new family of black hole initial data sets corresponding to distorted ``Kerr'' black holes with moderate rotation parameters, and distorted Schwarzschild black holes with even- and odd-parity radiation.

Black-Hole Remnants from Black-Hole–Neutron-Star Mergers [PDF]
Physical Review Letters, 2019 Observations of gravitational waves and their electromagnetic counterparts may soon uncover the existence of coalescing compact binary systems formed by a stellar-mass black hole and a neutron star. These mergers result in a remnant black hole, possibly surrounded by an accretion disk.

Black hole solutions surrounded by perfect fluid in Rastall theory
Physics Letters B, 2017 In this work, we obtain uncharged∖charged Kiselev-like black holes as a new class of black hole solutions surrounded by perfect fluid in the context of Rastall theory.

Primordial black holes—perspectives in gravitational wave astronomy [PDF]
, 2018 This article reviews current understanding of primordial black holes (PBHs), with particular focus on those massive examples (≳1015 g) which remain at the present epoch, not having evaporated through Hawking radiation. With the detection of gravitational

, 2014 We show that rapidly-spinning black holes can display turbulent gravitational behavior which is mediated by a new type of parametric instability.

Physical Review D, 1996 One would expect spacetime to have a foam-like structure on the Planck scale with a very high topology. If spacetime is simply connected (which is assumed in this paper), the non-trivial homology occurs in dimension two, and spacetime can be regarded as being essentially the topological sum of $S^2\times S^2$ and $K3$ bubbles.

Entropy of black holes with multiple horizons
Nuclear Physics B, 2018 We examine the entropy of black holes in de Sitter space and black holes surrounded by quintessence. These black holes have multiple horizons, including at least the black hole event horizon and a horizon outside it (cosmological horizon for de Sitter ...

, 1996 It is known that the naive version of D-brane theory is inadequate to explain the black hole entropy in the limit in which the Schwarzschild radius becomes larger than all compactification radii. We present evidence that a more consistent description can

International Journal of Modern Physics D, 2003 Production of high-energy gravitational objects is a common feature of gravitational theories. The primordial universe is a natural setting for the creation of black holes and other nonperturbative gravitational entities. Cosmic black holes can be used to probe physical properties of the very early universe which would usually require the knowledge of
