[ABRIDGED VERSION] The future of cm and m-wave astronomy lies with the Square Kilometre Array (SKA), a telescope under development by a consortium of 17 countries. The SKA will be…
NOIRCAT - The Northern HIPASS Optical/IR Catalogue
O. Ivy Wong, Rachel Webster, Virginia Kilborn +2
We present the Northern HIPASS Optical/InfraRed CATalogue (NOIRCAT), an optical/near-infrared counterpart to the Northern HIPASS catalogue (NHICAT). Of the 1002 sources in NHICAT,…
Is NGC 3108 transforming itself from an early to late type galaxy -- an astronomical hermaphrodite?
George Hau, Richard Bower, Virginia Kilborn +3
A common feature of hierarchical galaxy formation models is the process of "inverse" morphological transformation: a bulge dominated galaxy accretes a gas disk, dramatically reduci…
HI Mapping of Galaxies in Six GEMS Groups
Katie Kern, Virginia Kilborn, Duncan Forbes +1
Here we present Australia Telescope Compact Array HI maps of 16 HI sources in six Group Evolution Multiwavelength Study (GEMS) groups that were previously observed with the Parkes…
An HI survey of six Local Group analogs: I. Survey description and the search for high-velocity clouds
D. J. Pisano, D. G. Barnes, B. K. Gibson +3
We have conducted an HI 21 cm emission-line survey using the Parkes 20cm multibeam instrument and the Australia Telescope Compact Array (ATCA) of six loose groups of galaxies chose…
The Survey for Ionization in Neutral-Gas Galaxies: III. Diffuse, Warm Ionized Medium and Escape of Ionizing Radiation
M. S. Oey, G. R. Meurer, S. Yelda +7

The Northern HIPASS catalogue - Data presentation, completeness and reliability measures
O. I. Wong, E. V. Ryan-Weber, D. A. Garcia-Appadoo +32
The Northern HIPASS catalogue (NHICAT) is the northern extension of the HIPASS catalogue, HICAT (Meyer et al. 2004). This extension adds the sky area between the declination range…
The Arecibo Galaxy Environment Survey: Precursor Observations of the NGC 628 group
R. Auld, R. F. Minchin, J. I. Davies +25
The Arecibo Galaxy Environment Survey (AGES) is one of several HI surveys utilising the new Arecibo L-band Feed Array (ALFA) fitted to the 305m radio telescope at Arecibo. The surv…
Gaseous Tidal Debris found in the NGC 3783 Group
Virginia A. Kilborn, Duncan A. Forbes, Baerbel S. Koribalski +2
We have conducted wide-field HI mapping of a ~5.5 x 5.5 degree region surrounding the NGC 3783 galaxy group, to an HI mass limit of ~4 x 10^8 Msun. The observations were made using…
NGC922 - A new drop-through ring galaxy
O. I. Wong, G. R. Meurer, K. Bekki +26
We have found the peculiar galaxy NGC922 to be a new drop-through ring galaxy using multi-wavelength (UV-radio) imaging and spectroscopic observations. Its `C'-shaped morphology an…
The Survey for Ionization in Neutral Gas Galaxies- II. The Star Formation Rate Density of the Local Universe
D. J. Hanish, G. R. Meurer, H. C. Ferguson +19
We derive observed Halpha and R band luminosity densities of an HI-selected sample of nearby galaxies using the SINGG sample to be l_Halpha' = (9.4 +/- 1.8)e38 h_70 erg s^-1 Mpc^-3…
Southern GEMS Groups I: Dynamical Properties
Sarah Brough, Duncan Forbes, Virginia Kilborn +1
Here we present an investigation of the properties of 16 nearby galaxy groups and their constituent galaxies. The groups are selected from the Group Evolution Multi-wavelength Stud…
The Survey for Ionization in Neutral Gas Galaxies: I. Description and Initial Results
Gerhardt R. Meurer, D. J. Hanish, H. C. Ferguson +19
We introduce the Survey for Ionization in Neutral Gas Galaxies (SINGG), a census of star formation in HI-selected galaxies. The survey consists of H-alpha and R-band imaging of a s…
Eridanus - A Supergroup in the Local Universe?
Sarah Brough, Duncan Forbes, Virginia Kilborn +2
We examine a possible supergroup in the direction of the Eridanus constellation using 6dF Galaxy Survey second data release (6dFGS DR2) positions and velocities together with 2MASS…
HI in Local Group analogs: what does it tell us about galaxy formation?
D. J. Pisano, D. Barnes, B. Gibson +3
We present the results of our HI survey of six loose groups of galaxies analogous to the Local Group. The survey was conducted using the Parkes telescope and the Australia Telescop…
The Group Evolution Multiwavelength Study (GEMS): the Sample and Datasets
Duncan A. Forbes, Trevor Ponman, Frazer Pearce +7
Galaxy groups have been under-studied relative to their richer counterparts -- clusters. The Group Evolution Multiwavelength Study (GEMS) aims to redress some the balance. Here we…
