Effective temperature for black holes
Black hole entropy Hawking radiation eff ective temperature
2011/10/14
The physical interpretation of black hole's quasinormal modes is fundamental for realizing unitary quantum gravity theory as black holes are considered theoretical laboratories for testing models of s...
Assessing the redshift evolution of massive black holes and their hosts
quasars: general { galaxies: evolution { galaxies: formation { black hole physics
2011/9/30
Motivated by recent observational results that focus on high redshift black holes, we explore the effect of scatter and observational biases on the ability to recover the intrinsic properties of the b...
The interior structure of astronomically realistic rotating black holes 2. Uncharged black holes
The interior structure black holes
2011/1/13
An exact solution is obtained for the interior structure of a uncharged rotating black hole that accretes a collisionless fluid. The solutions are conformally stationary, axisymmetric, and separable. ...
Probing Intermediate Mass Black Holes With Optical Emission Lines from Tidally Disrupted White Dwarfs
Probing Intermediate Mass Black Holes Optical Emission Lines
2011/1/13
We calculate the emission line spectrum produced by the debris released when a white dwarf (WD) is tidally disrupted by an intermediate-mass black hole (IMBH; $M\sim 10^{2}-10^{5}\msun$) and we explor...
Search of sub-parsec massive binary black holes through line diagnosis
sub-parsec binary black holes
2011/1/10
We investigate on the spectral properties of an active black hole, member of a massive (10^7 - 10^9 Msun) sub-parsec black hole binary. We work under the hypothesis that the binary, surrounded by a ci...
Cosmological evolution of massive black holes: effects of Eddington ratio distribution and quasar lifetime
Galaxy Astrophysics (astro-ph.GA)
2010/12/22
A power-law time-dependent lightcurve for active galactic nuclei (AGNs) is expected by the self-regulated black hole growth scenario, in which the feedback of AGNs expels gas and shut down accretion. ...
We calculate intensity of thermal radiation (via Hawking effect) and evaporation time of a stationary nonrotating black hole using Kirchhoff's law and the electrodynamic membrane paradigm. It is shown...
Production of tidal-charged black holes at the Large Hadron Collider
Tidal-charged black hole Large Hadron Collider
2010/3/18
Tidal-charged black hole solutions localized on a three-brane in the five-dimensional gravity scenario of Randall and Sundrum have been known for some time. The solutions have been used to study the d...
