AbstractObservations with Spitzer of Stephan’s Quintet, the Taffy galaxies and several other Hickson Compact Groups showed evidence for enhanced warm molecular rotational lines of hydrogen which suggest strong heating in shocks and turbulence. We present new Herschel, CARMA and Chandra data of several systems which support the idea that shock/turbulent heating is present in these systems, through a study of the far-IR cooling lines, X-ray luminosity and peculiar CO dynamics. We show that SPICA/SAFARI is capable of detecting rotational molecular hydrogen from the brightest known H2 emitting galaxies (Zw 3146 and the “Spiderweb”) to 0.5 less than z less than 6 if they exist there, or if less luminous systems are significantly lensed. Turbulent systems may be common at high-z where the most extreme objects are likely to lie in the largest massive dark-matter halos.
