Cosmological multi-black-hole solutions
Einstein Maxwell equation the charged black holes time and space actively the cosmological constant a black hole
2014/12/23
We present simple, analytic solutions to the Einstein-Maxwell equation, which describe an arbitrary number of charged black holes in a spacetime with a positive cosmological constant Λ. In the limit Λ...
Testing cosmic censorship with black hole collisions
Quality of the hole the cosmological constant total quality extreme limit
2014/12/23
There exists an upper limit on the mass of black holes when the cosmological constant Λ is positive. We study the collision of two black holes whose total mass exceeds this limit. Our investigation is...
U duality, D-branes, and black hole emission rates: Agreements and disagreements
Absorption coefficient five dimensions scalar field a black hole the parameter space
2014/12/22
An expression for the spacetime absorption coefficient of a scalar field in a five-dimensional, near-extremal black hole background is derived, which has the same form as that presented by Maldacena a...
The thermodynamics of Kaluza–Klein black hole/bubble chains
Bubble surface black holes time and space exchange said sex black hole static
2014/12/19
A Killing bubble is a minimal surface that arises as the fixed surface of a spacelike Killing field. We compute the bubble contributions to the Smarr relations and the mass and tension first laws for ...
Searches For Gravitational Waves From Binary Black Hole Coalescences With Ground-based Laser Interferometers Across a Wide Parameter Space
Binary Black Hole Data Analysis Gravitational-Waves LIGO NINJA Signal Processing
2014/11/20
This is an exciting time for Gravitational Wave (GW) theory and observations. From a theoretical standpoint, the grand-challenge problem of the full evolution of a Binary Black Hole (BBH) system has b...
A new study shows what happens during the destruction of a star as it falls into a black hole, contradicting a 2012 report of the disruption of an exotic helium star.
Is it possible to create a quantum electromagnetic "black hole" at the Large Hadron Collider?
quantum electromagnetic "black hole" Large Hadron Collider Optics
2012/4/19
As demonstrated by Chernodub, strong magnetic field forces vacuum to develop real condensates of electrically charged rho mesons, which form an anisotropic inhomogeneous superconducting state similar ...

Thermodynamics of phantom energy in the presence of a Reissner-Nordstrom black hole
Phantom energy Reissner-Nordstr¨om black hole Generalized second law of thermodynamics
2011/8/31
In this paper, we study the validity of the generalized second law (GSL) in phantom dominated universe in the presence of a Reissner-Nordstr¨om (RN) black hole. Our study is independent of the origin ...
Evolution of massive fields around a black hole in Horava gravity
Evolution of massive fields black hole Horava gravity
2010/12/20
We study the time evolution of massive scalar field in the spacetime geometry of Kehagias-
Sfetsos(KS) black hole in deformed Hoˇrava-Lifshitz(HL) gravity by numerical analysis. We find
that the sig...
Reconstructing the massive black hole cosmic history through gravitational waves

2010/12/21
The massive black holes we observe in galaxies today are the natural end-product of a complex
evolutionary path, in which black holes seeded in proto-galaxies at high redshift grow through
cosmic hi...
Schwarzschild-de Sitter black hole from entropic viewpoint
Schwarzschild-de Sitter black hole entropic viewpoint
2010/12/23
In a Schwarzschild-de Sitter space, we consider an equipotential surface which consists of two holographic screens. Adapting the Bousso-Hawking's reference point of vanishing force, we divide the spac...
Black Hole Entropy, Loop Gravity, and Polymer Physics
Black Hole Entropy Loop Gravity Polymer Physics
2010/12/27
Loop Gravity provides a microscopic derivation of Black Hole entropy. In this paper, I show that the microstates counted admit a semiclassical description in terms of shapes of a tessellated horizon. ...
State independence for tunneling processes through black hole horizons and Hawking radiation
State independence black hole horizons Hawking radiation
2010/12/27
Tunneling processes through black hole horizons have recently been investigated in the framework of WKB theory discovering interesting interplay with the Hawking radiation. In this paper we instead ad...

2010/12/23
We construct finite mass, asymptotically flat black hole solutions in d=5 Einstein--Yang-Mills--Chern-Simons theory. Our results indicate the existence of a second order phase transition between Reiss...
