We present preliminary results from HI observations of a new sample of compact groups done with the Parkes telescope, as well as from images made with the Australia Telescope Compact Array (ATCA). These observations confirm earlier claims that a significant fraction of compact groups are deficient in HI, and hence that a significant fraction of groups of galaxies that appear compact on the sky are indeed compact systems. ...

... Increases in IR surface brightness appear to be affected by both increased radiation field strength and increased local gas density. Individual regions and the galaxy as a whole fall within the observed scatter of recent high-resolution studies of the radio-far-IR correlation in nearby spiral galaxies; this is likely the result of depleted radio and far-IR emission strengths in the ISM of this dwarf galaxy. ...

... While space seems to be expanding at present (just as in our own universe), this expansion seems to be a recent phenomenon: in the past it appears to have been contracting. Data It is now clear that fuzzballs are actually galaxies. ... For the brightest fuzzballs, those from which we detect more than 100 photons per second, the pattern seems to match what we would expect. The fuzzball galaxies are indeed redshifted, and the fainter ones are more redshifted than the bright (nearby) ones. ...
