J/A+A/449/929       HI observations of Coma Supercluster        (Gavazzi+, 2006)

HI observations of galaxies. II. The Coma Supercluster. Gavazzi G., O'neil K., Boselli A., Van Driel W. <Astron. Astrophys., 449, 929-935 (2006)> =2006A&A...449..929G
ADC_Keywords: Clusters, galaxy ; H I data; Galaxies, radio Keywords: galaxies: distances and redshifts - galaxies: general - galaxies: ISM - galaxies: clusters: individual: Virgo - radio lines: galaxies Abstract: High sensitivity 21-cm HI line observations with an rms noise level of ∼0.5mJy were made of 35 spiral galaxies in the Coma Supercluster, using the refurbished Arecibo telescope, leading to detection of 25 objects. These data, combined with the measurements available in the literature, provide the set of HI data for 94% of all late-type galaxies in the Coma Supercluster with an apparent photographic magnitude mp≤15.7mag. We confirm that the typical scale of HI deficiency around the Coma cluster is 2Mpc, i.e. one virial radius. Comparing the HI mass function (HIMF) of cluster with non-cluster members of the Coma Supercluster we detected a shortage of high HI mass galaxies among cluster members that can be attributed to the pattern of HI deficiency found in rich clusters. Description: Using the refurbished 305-m Arecibo Gregorian radio telescope, we observed 35 galaxies in the Coma Supercluster, (plus 13 in the Virgo cluster) (see Sect. 2) in February 2004 and January-March 2005.
