| « The warm-hot circumgalactic medium » |

Smita Mathur |
| 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'll review our progress so far, highlight new discoveries, outline the open questions, and discuss paths for future progress. |
