Gravitational waves detected from second pair of colliding black holes
Gravitational waves second pair colliding black holes
2016/6/22
On Dec. 26, 2015 at 03:38:53 UTC, scientists observed gravitational waves -- ripples in the fabric of spacetime -- for the second time.
The gravitational waves were detected by both of the twinLaser ...
Superkicks in ultrarelativistic encounters of spinning black holes
Superkicks ultrarelativistic encounters spinning black holes
2010/12/20
We study ultrarelativistic encounters of two spinning, equal-mass black holes through simulations in full numerical relativity. Two initial data sequences are studied in detail: one that leads to scat...
Holographic Q-Picture of Black Holes in Five Dimensional Minimal Supergravity
Holographic Q-Picture Black Holes Five Dimensional Minimal Supergravity
2010/12/21
In this article, we explore the holographic Q-picture description for the charged rotating black holes in the five-dimensional minimal supergravity. The central charge in the Q-picture depends only on...
In this paper, we classify and construct five-dimensional black holes on gravitational instantons in vacuum Einstein gravity, with R × U(1) × U(1) isometry. These black holes have
spatial backgrounds...
Topological geon black holes in Einstein-Yang-Mills theory
Topological geon black holes Einstein-Yang-Mills theory
2010/3/18
We construct topological geon quotients of two families of Einstein-Yang-Mills black holes. For Kuenzle's static, spherically symmetric SU(n) black holes with n>2, a geon quotient exists but generical...
In the context of $f(R)$ gravity theories, the issue of finding static and spherically symmetric black hole solutions is addressed. Two approaches to study the existence of such solutions are consider...
Thin-shell wormholes from charged black holes in generalized dilaton-axion gravity
Thin-shell wormholes black holes
2010/3/17
This paper discusses a new type of thin-shell wormhole constructed by applying the cut-and-paste technique to two copies of a charged black hole in generalized dilaton-axion gravity, which was inspire...
