Discovery of an Unusual Dwarf Galaxy in the Outskirts of the Milky Way
M. J. Irwin, V. Belokurov, N. W. Evans +24
In this Letter, we announce the discovery of a new dwarf galaxy, Leo T, in the Local Group. It was found as a stellar overdensity in the Sloan Digital Sky Survey Data Release 5 (SD…
Local Galaxies as Damped Ly-Alpha Analogs
M. A. Zwaan, J. M. van der Hulst, F. H. Briggs +2
We calculate in detail the expected properties of low redshift DLA systems under the assumption that they arise in the gaseous disks of galaxies like those in the z=0 population. A…
The HIPASS Catalogue - I. Data Presentation
M. J. Meyer, M. A. Zwaan, R. L. Webster +9
The HI Parkes All-Sky Survey (HIPASS) Catalogue forms the largest uniform catalogue of HI sources compiled to date, with 4,315 sources identified purely by their HI content. The ca…
Recycling of ghost galaxies: The origin of giant HI ring around NGC 1533
Kenji Bekki, Warrick J. Couch, Emma Ryan-Weber +1
We propose that the giant HI ring recently discovered by HIPASS for S0 galaxy NGC 1533 is formed by unequal-mass merging between gas-rich LSB (low surface brightness: ``ghost'') ga…
The 1000 Brightest HIPASS Galaxies: Newly Cataloged Galaxies
E. Ryan-Weber, B. S. Koribalski, L. Staveley-Smith +6
The HI Parkes All-Sky Survey (HIPASS) is a blind 21-cm survey for extragalactic neutral hydrogen, covering the whole southern sky. The HIPASS Bright Galaxy Catalog (BGC; Koribalski…
Local Column Density Distribution Function from HI selected galaxies
Emma Ryan-Weber, Rachel Webster, Lister Staveley-Smith
The cross-section of sky occupied by a particular neutral hydrogen column density provides insight into the nature of Lyman-alpha absorption systems. We have measured this column d…
