NED Abstract

Copyright by Royal Astronomical Society. 1997MNRAS.288..307B An H I survey for protogalaxies in the Centaurus and Fornax galaxy clusters D. G. Barnes, L. Staveley-Smith, R. L. Webster and W. Walsh Accepted 1997 January 13. Received 1996 December 11; in original form 1996 August 19 ABSTRACT The results of 21 -cm neutral hydrogen survey observations, made using the 64-m Parkes telescope, are presented for two 8^deg^ by 8^deg^ fields, centred on the Centaurus and Fornax galaxy clusters, and a smaller 1.5^deg^ field in Eridanus. The purpose of the observations was to search for extended HI clouds with no clear optical counterparts. 31 previously catalogued galaxies were detected, with HI parameters for 16 being listed for the first time. One previously uncatalogued dwarf galaxy (`Wombat I', 30341-3851) was found near the Fornax cluster. Australia Telescope Compact Array observations give an HI mass of 8 x 10^7^ M_sun_ and a diameter of 4 kpc for this object, which is also visible on UKST survey plates. However, no clouds with optically invisible counterparts were detected. We deduce a 99 per cent confidence limit on the total HI density of such objects in the cluster and near-cluster environment of {OMEGA}_HI_ < 10^-2^h^-1^({delta}V/100 km s^-1^). Key words: surveys - galaxies: clusters: individual: Centaurus - galaxies: clusters: individual: Eridanus - galaxies: clusters: individual: Fornax - radio lines: galaxies.
