On the Origin of High-velocity Clouds in the Galaxy

The origin of our Galaxy’s high-velocity clouds (HVCs) remains a mystery after many decades of effort. In this paper, we use the TNG50 simulation of the IllustrisTNG project to identify cool, dense clouds that match observations of Galactic H i HVCs. We track these clouds back in time to determine t...
