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...

Black-Hole Solutions to Einstein's Equations Presence of Matter Modifications of Gravitation
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...

2010/3/18
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...
Regularization parameters for the self-force of a scalar particle in a general orbit about a Schwarzschild black hole
scalar particle Schwarzschild black hole
2010/3/18
The interaction of a charged particle with its own field results in the "self-force" on the particle, which includes but is more general than the radiation reaction force. In the vicinity of the parti...

f(R)Gravity Modified gravity Spherical Symmetry
2010/3/18
A static, asymptotically flat, spherically symmetric solutions is investigated in f(R) theories of gravity for a charged black hole. We have studied the weak field limit of f(R) gravity for the some f...
