My research focuses on studying the extremely luminous objects (more than a billion times the solar luminosity) called active galactic nuclei (AGNs). Many of these objects are hidden behind dust and gas. Dusty starburst discs could explain the obscuration of active galactic nuclei (AGNs) at intermediate redshift when a large gas fraction is available in galaxies. My work involves the numerical modeling of these regions (2D structure) from the scratch which includes solving non-linear second order differential equation (boundary value problem) using finite-difference method, a set of coupled equations using iterative method, and non-linear flux conservative equation using various schemes. The end goal is to predict the observables such as column density along a line of sight, the equivalent width of the FeKα line, Cosmic X-ray background, and Cosmic Infrared background which can be tested against observations.
