HI-deficiency in Hickson compact groups of galaxies.
Abstract
We present HI observations of 54 Hickson Compact Groups (HCG) of which 41 have been detected in the 21-cm line of neutral hydrogen. For 13 objects upper limits have been obtained. The integrated M_HI_/L_B_ values of the observed HCGs scatter over a large range of values showing strong HI-deficiencies for a great number of objects.
