Pedron R. da Rocha Física, Astronomía y Matemáticas The aim of this work is to present a possible way to estimate observational electromagnetical clues in thespectrum of quasars and microquasars due to the presence of extra dimensions. Here we analyze two possibleways to detect these electromagnetic signals: by the brane corrected accretion mechanism and by production ofelectromagnetic KK modes. We show that for the static black hole accretion case, the brane corrections cause aextremelly small variation in the luminosity of the quasar. For the electromagnetic KK modes case, apparentlythe answer for the biggest quasars is positive and on the other hand, the possibility that microquasars can presentconstraints on extra-dimensional gravity in their spectra is less probable. 2005 artículo científico 0103-9733 https://www.redalyc.org/articulo.oa?id=46435731 en http://www.redalyc.org/revista.oa?id=464 Brazilian Journal of Physics application/pdf Sociedade Brasileira de Física Brazilian Journal of Physics (Brasil) Num.4B Vol.35 |
