Hello, I am Katrin Lehle, a current PhD candidate at the Institute for Theoretical Astrophysics, Heidelberg University. Under the guidance of Dylan Nelson, I hold a position funded by the Hector-Fellow-Academy. Additionally, I am a fellow at the International Max Planck Research School for Astronomy and Cosmic Physics in Heidelberg. My research focus is centered on the gaseous intracluster medium (ICM) within galaxy clusters, with a particular emphasis on the central region and the cooling properties of the cores. To gain insight into the complex physics of galaxy clusters, I analyze cosmological galaxy formation simulations such as TNG-Cluster and IllustrisTNG.
