Warm Gas and Ionizing Photons in the Local Group (ApJL version)
Philip R. Maloney, J. Bland-Hawthorn
Several lines of argument suggest that a large fraction of the baryons in the universe may be in the form of warm (T\sim 10^5-10^7 K) gas. In particular, loose groups of galaxies m…
High-Redshift Gravitationally Lensed Galaxies and Tunable Filter Imaging
Paul C. Hewett, Stephen J. Warren, Jon P. Willis +2
Most surveys for multiply-imaged gravitational lenses, outside of rich galaxy clusters, are based on sifting through large samples of distant sources to identify the rare examples…
The 2dF Galaxy Redshift Survey: Spectral Types and Luminosity Functions
S. R. Folkes, S. Ronen, I. Price +22
We describe the 2dF Galaxy Redshift Survey (2dFGRS), and the current status of the observations. In this exploratory paper, we apply a Principal Component Analysis to a preliminary…
Towards a Direct Detection of Warm Gas in Galactic Haloes at Cosmological Distances
Milan M. Cirkovic, J. Bland-Hawthorn, Srdjan Samurovic
Recent highly sensitive detections of line emission from extended gas in the local universe demonstrate the feasibility of detecting H emitting galactic halos out to . W…
