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.
