Brownian motion of black holes in stellar systems with non-Maxwellian distribution for the stars field
I. T. Pedron, C. H. Coimbra-Araujo
A massive black hole at the center of a dense stellar system, such as a globular cluster or a galactic nucleus, is subject to a random walk due gravitational encounters with nearby…
A thin disk in higher dimensional space-time and dark matter interpretation
Carlos H. Coimbra-Araujo, Patricio S. Letelier
We find a family of exact solutions of Einstein equations describing the field of a static axisymmetric thin disk living in six-dimensional space-time. In particular, we study the…
Physical Effects of Extra Dimension and Concomitant Map between Photons and Gravitons in Randall-Sundrum Brane-World Scenario
Roldao da Rocha, Carlos H Coimbra-Araujo
We investigate, in Randall-Sundrum braneworld scenario, the relationship between perturbations of gravitational and electromagnetic waves in a black hole neighboorhood, proposing a…
Could the variation in quasar luminosity, due to extra dimension 3-brane in RS model, be measurable?
Roldao da Rocha, Carlos H. Coimbra-Araujo
We propose an alternative theoretical approach showing how the existence of an extra dimension in RS model can estimate the correction in the Schwarzschild radius of black holes, a…
Anti-de Sitter curvature radius constrained by quasars in brane-world scenarios
Carlos H. Coimbra-Araujo, Roldao da Rocha, I. T. Pedron
This paper is intended to investigate the luminosity due to accretion of gas in supermassive black holes (SMBHs) in the center of quasars, using a brane-world scenario naturally en…
