A Herschel and CARMA view of CO and [C II] in Hickson Compact groups

Understanding the evolution of galaxies from the starforming blue cloud to the quiescent red sequence has been revolutionized by observations taken with Herschel Space Observatory, and the onset of the era of sensitive millimeter interferometers, allowing astronomers to probe both cold dust as well as the cool interstellar medium in a large set of galaxies with unprecedented sensitivity. Recent Herschel observations of of H-2-bright Hickson Compact Groups of galaxies (HCGs) has shown that [C II] may be boosted in diffuse shocked gas. CARMA CO(1-0) observations of these [C II]-bright HCGs has shown that these turbulent systems also can show suppression of SF. Here we present preliminary results from observations of HCGs with Herschel and CARMA, and their [C II] and CO(1-0) properties to discuss how shocks influence galaxy transitions and star formation.
