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

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

After the Interaction: an Efficiently Star-forming Molecular Disk in NGC5195

Most of the blogs that have already been written here discuss the unexpected. Gas in "red and dead" galaxies or molecular outflow hosts
Observations of hydroxyl in early-type galaxies

Observations of hydroxyl in early-type galaxies

This paper is quite special to me, because it was a fishing expedition that seemed unlikely to detect anything, and then nature and the universe

The ATLAS3D Project - XIV. The extent and kinematics of the molecular gas in early-type galaxies

We continue our exploration of the molecular gas properties of early-type galaxies, which I have already blogged about here, here, and here. In this case,
Evidence of boosted 13CO/12CO ratio in early-type galaxies in dense environments

Evidence of boosted 13CO/12CO ratio in early-type galaxies in dense environments

Last blog we learned about the strange things happening to gas in dense environments, like the Virgo cluster. This blog, we are going to continue
