Title: The Circumgalactic Medium at 200 pc

Abstract: The circumgalactic medium (CGM) plays a crucial role in the baryon cycle by mediating all of the gas flows in and out of the galaxy. However, simulating this region is difficult due to its immense volume and low densities. Fixed spatial resolution is an excellent tool to overcome this problem. In this talk, I will introduce a new suite of cosmological zoom simulations with 200 pc resolution covering the inner CGM of a Milky Way-mass galaxy, utilizing the full IllustrisTNG galaxy formation model. At this high resolution, we find increased turbulent velocities, many small, cold cloudlets, and an intricately structured hot phase.
