On the HI column density - radio source size anti-correlation in compact radio sources
S. J. Curran, J. R. Allison, M. Glowacki +2
Existing studies of the atomic hydrogen gas content in distant galaxies, through the absorption of the 21-cm line, often infer that the total column density is anti-correlated with…
Probing the cool ISM in galaxies via 21cm HI absorption
J. R. Allison, E. M. Sadler, S. J. Curran +1
Recent targeted studies of associated HI absorption in radio galaxies are starting to map out the location, and potential cosmological evolution, of the cold gas in the host galaxi…
A search for 21 cm HI absorption in AT20G compact radio galaxies
J. R. Allison, S. J. Curran, B. H. C. Emonts +7
We present results from a search for 21 cm associated HI absorption in a sample of 29 radio sources selected from the Australia Telescope 20 GHz survey. Observations were conducted…
Application of a Bayesian Method to Absorption Spectral-Line Finding in Simulated ASKAP Data
J. R. Allison, E. M. Sadler, M. T. Whiting
The large spectral bandwidth and wide field of view of the Australian SKA Pathfinder radio telescope will open up a completely new parameter space for large extragalactic HI survey…
A parametric physical model for the intracluster medium and its use in joint SZ/X-ray analyses of galaxy clusters
J. R. Allison, A. C. Taylor, M. E. Jones +2
We present a parameterized model of the intra-cluster medium that is suitable for jointly analysing pointed observations of the Sunyaev-Zel'dovich (SZ) effect and X-ray emission in…
