There are a lot of very interesting astrophysical problems arround AGN(Active Galactic Nuclei). People believe there is one or several super massive astrophysical objects at the center of every galaxy. They could be blackholes, neutral stars and even those haven't got names yet. One way to study the intrinsic and dynamic properties of those objects is to detect the high energy radiations(X rays, Gamma rays) from those objects. Another way is to do theoretical analysis based on existing theories and experiments. Numerical simulations work as bridges between them.
What I am doing is to simulate two colliding jets and study the radiations emited. My work is based on two existing codes. One is able to do SRMHD(Special Relativistic Magnetohydradynamics) simulations of relativistic jets and the other one is able to calculate radiations from known physical data. By considering many micro physics phenomena which are supposed to be triggered in that condition, we will be able to tell which micro physics phenomenon is more important to generate observed data and in some sense determine the basic mechanism causing certain astrophysical phenomenon.
