A multi-beam HI survey of the Virgo Cluster - two isolated HI clouds ?
J. Davies, R. Minchin, S. Sabatini +11
We have carried out a fully sampled large area () 21cm \HI line survey of part of the Virgo cluster using the Jodrell Bank multi-beam instrument. The su…
Properties of three gas-rich dwarfs in the Centaurus A group
M. Grossi, M. J. Disney, B. J. Pritzl +5
We present HST/WFPC2 observations (F555W, F814W) and ATCA high resolution HI maps of three gas-rich dwarf galaxies in the Centaurus A group discovered in two blind 21-cm surveys (H…
HIDEEP - An extragalactic blind survey for very low column-density neutral hydrogen
R. F. Minchin, M. J. Disney, P. J. Boyce +13
We have carried out an extremely long integration-time (9000 s/beam) 21-cm blind survey of 60 square degrees in Centaurus using the Parkes multibeam system. We find that the noise…
Anomalous Evolution of the Dwarf Galaxy HIPASS J1321-31
Barton J. Pritzl, Patricia M. Knezek, John S. Gallagher +6
We present HST/WFPC2 observations of the dwarf galaxy HIPASS J1321-31. This unusual galaxy lies in the direction of the Centaurus A group of galaxies, and has a color-magnitude dia…
The 1000 Brightest HIPASS Galaxies: HI Mass Function and Omega_HI
M. A. Zwaan, L. Staveley-Smith, B. S. Koribalski +37
We present a new accurate measurement of the HI mass function of galaxies from the HIPASS Bright Galaxy Catalog, a sample of 1000 galaxies with the highest HI peak flux densities i…
First Results from the HI Jodrell All Sky Survey: Inclination-Dependent Selection Effects in a 21-cm Blind Survey
R. H. Lang, P. J. Boyce, V. A. Kilborn +8
Details are presented of the HI Jodrell All Sky Survey (HIJASS). HIJASS is a blind neutral hydrogen (HI) survey of the northern sky, being conducted using the multibeam receiver on…
