I study the mechanisms behind magnetically-driven astrophysical jets from black holes using supercomputer simulations. These jets are relativistic plasma outflows launched from active galactic nuclei (AGNs), the energetic cores found at the centers of galaxies. Despite decades of research, the driving mechanism of AGN jets remains one of the major unsolved mysteries in modern astrophysics. The leading hypothesis is that they are powered by the interaction between a supermassive black hole and the magnetic fields threading its surrounding accretion flow. With this in mind, my research focuses on extracting information about these magnetic fields from high-resolution images near the black hole.
