Emission Line Mapping of the Circumgalactic Medium of Nearby Galaxies
Abstract
The circumgalactic medium (CGM) is both the reservoir of gas for subsequent star formation and the depository of chemically processed gas, energy, and angular momentum from feedback. We discuss the opportunity to realize spectral-line images of the CGM in individual nearby galaxies. Such work will happen in the next decade.
