S. Silich: Super-massive star clusters: from superwinds to cooling catastrophe to the injected gas reprocessing
How quickly does the gas that is heated by the SSC cool? The larger the cluster the more radiative cooling (I did not understand why) and eventually there is a regime of "catastrophic cooling" where no equilibrium solution exists any more.
Studies in M82 which blows a huge bipolar wind perpendicular to the disk (pretty picture) show that .... I missed it because I fetched the link to the picture. :-)
