Abstract
The circumgalactic medium (CGM) is an important component of a galaxy, at the interface between the intergalactic medium and the galactic disk, playing a critical role in galaxy formation and evolution. The X-ray missions Chandra, XMM-Newton, and Suzaku opened a new window on CGM studies, allowing us to probe the warm-hot gas where most of the galactic baryons reside. In over two decades since the launch of the great X-ray observatories, we have made great strides in understanding the CGM, but significant challenges remain. I will review our progress so for, highlight new discoveries, outline the open questions, and discuss paths for future progress.
