Abstract

What can be the most grandeur encounter in the universe? Imagine when the most massive black holes processing energetic outflows of relativistic particles, meet with galaxy clusters, the largest structures bound by gravity. Those enormous galaxy clusters host superheated X-ray emitting gas between the thousands of galaxies. Only as the gas cools down over cosmic time do stars take form. It has been a long-standing mystery in cosmology, however, that we observe fewer stars than the theory predicts. As further studies have shown, the supermassive black holes in the center of these clusters, otherwise known as active galactic nuclei (AGNs), are the main sources that regulate galaxy formation by setting the rate at which gas becomes available to form stars. These black holes, according to General Relativity, cause the hot magnetospheric plasma to form accretion disks and furtherly, magnetically driven jets and outflows. Facilitated by the newest supercomputers, we are developing a new generation of physics models through which we will be able to simulate a variety of physical processes, and provide insights into the interplay between the jet and its surrounding interstellar medium. With this research, we endeavor to understand how galaxies have evolved into what we've been observing today.
