Star Formation Suppression in Compact Group Galaxies: a New Path to Quenching?

We've covered suppression, and we've now had an introduction to Hickson Compact groups. This all started with HCG 57a and d... and the idea that turbulence within some of these compact group systems has the potential to inhibit star formation in the molecular gas. Here we

Strong Far-Infrared Cooling Lines, Peculiar CO Kinematics, and Possible Star-formation Suppression in Hickson Compact Group 57

If I needed to come up with a single sentence to describe this paper, it would be "deconstructing an interaction to understand its physics piece by piece." That sort of paper follows from the NGC5195 blog, but we are now moving to bigger galaxies and more complicated distributions.
