|Title:||Anti-de sitter curvature radius constrained by quasars in brane-world scenarios|
Da Rocha, R
|Abstract:||This paper is intended to investigate the luminosity due to the accretion of gas in super-massive black holes (SMBHs) in the center of quasaxs, using a brane-world scenario naturally endowed with extra dimensions, whereon theories formulated introduce corrections in the field equations at high energies. SMBHs possess the necessary highly energetic environment for the introduction of these corrections, which axe shown to produce small deviations in all SMBH properties and, consequently, corrections in the accretion theory that supports quasars radiative processes. The radiative flux observed from quasars indicates these deviations, from which the magnitude of the AdS(5) bulk curvature radius, and consequently the extra dimension compactification radius is estimated.|
