Dynamics of relativistic jets around active galactic nuclei in schwarzschild de sitter geometry

Abstract

More recent literature reviews point out that most galaxies, especially early type galaxies with Active Galactic Nuclei (AGN), contain Massive Black Holes (MBHs)considered to be comparable to the masses of high redshift quasars to the evolution of early galaxies. Some of these sources seem to accrete and eject matter-energy at a very high rate as reported. As a result it was believed that Electromagnetic(EM) spectrum observations are required to provide information on black holes in the centers of active galaxies. On the other hand, Gravitational Wave(GW) observations are considered to provide the complementary information about the capture of particles including compact objects like Black Holes(BHs) that are mostly invisible to EM observations. Thus, the astrophysical study of AGNs in its full relativistic effect is active and fresh research. For example, the efficient mechanisms to describe the energy - momentum and jets flow that could be exploited to match observations are important and open to research. Motivated by this scientific background, We worked on the dynamics of relativistic jets flow around AGNs by considering full General Relativity equations of charged fluid in Schwarzschild-de sitter geometry. The relevant dynamical parameters like pressure were being derived by setting simplifying boundary conditions. Finally we had work out on numerical analysis of the derived observable quantities to check their significance. In particular the pressure p B and PΛ in terms of radial distance from AGN was in agreement with the existing theory. The pressure due to magnetic field was, the dominant pressure at the surface of black hole horizon, is important for the formation of relativistic jets around AGN and far from black hole horizon pressure due to cosmology constant becomes dominant because of the effects of cosmology constant. Finally cosmology constant was a significant effects in local gravitating objects geometric structure and pressure. .
