Solving the Mysteries of Galaxy and Supermassive Black Hole Formation in the Era of High-resolution Simulations and Machine Learning

Author(s):

Presenter: Ji-hoon Kim (Seoul National University)

The community of numerical galaxy formation has benefited greatly from the ever-improving computing technology over the past decades. I will discuss the new possibilities in the upcoming era of high-resolution numerical galaxy formation and machine learning, and highlight efforts to overcome the accompanying challenges. As one example, I will describe a state-of-the-art cosmological simulation of a high-redshift quasar-host galaxy that includes sophisticated treatments of feedback from star-forming clumps and supermassive black holes (SMBHs). I will demonstrate that previously undiscussed types of interplay between galactic components may hold important clues about the growth of SMBHs. In another example, I will introduce a machine-assisted pipeline that estimates baryonic properties of a galaxy based purely on its dark matter (DM) properties in a large-scale DM-only simulation.
