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...

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...

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 ...

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
massive black hole cosmic history 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...
Black Hole Entropy, Loop Gravity, and Polymer Physics
Black Hole Entropy Loop Gravity d Polymer Physics
2010/12/20
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....

2010/12/20
In this paper, we study a regular Bardeen black hole as a gravitational lens. We find the strong deflection limit for the deflection angle, from which we obtain the positions and
magnifications of th...

2010/12/21
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...

2010/12/21
In this thesis, we wish to examine the black-hole solutions of modi ed gravity theories inspired by String Theory or Cosmology. Namely, these modi cations will take the guise of additional gauge and s...

2010/12/21
We study the motion of charged test particles around a Kerr black hole immersed in the asymptotically uniform magnetic field, concluding that off-equatorial stable orbits are allowed in this system. B...

In this work we investigate gravitational lensing effect in strong field region around a dilaton black holes in an anti de Sitter (ADS) space. We also analyse the dependence of the radius of the photo...
Using the Wald's relation between the Noether charge of diffeomorphisms and the entropy for a generic spacetime possessing a bifurcation surface, we introduce a method to obtain a family of higher ord...
