[50.01] The HI Content of Poor Groups of Galaxies: HCG 22

K. M. Kern, Eric M. Wilcots (U. Wisconsin)

We present a 21cm HI mosaic of the HCG 22 poor group of galaxies. HCG 22 differs from most well-studied groups in that it lacks diffuse x-ray emission. We detected two of the three major spirals, but none of the ellipticals or S0. Most suprisingly we have detected a cloud of intergalactic HI, with a HI mass of 1.39X10⁸ solar masses. The intragroup gas may be a possible remnant of previous tidal interactions.
