| Abstract | A total of 44 galaxies in the direction of the Virgo and Coma/Abell 1367 Clusters have been observed in the H I line at Nançay, 17 of which were clearly detected. These observations were obtained in order to complete the H I database for a large, optically selected, sample of galaxies in these two regions. Surveys in these regions at other wavelengths (UV, visible, near-, mid- and far-infrared, radio continuum) have been recently completed or are still underway. |
