Tracing X-ray and HI absorption in peaked spectrum sources
Emily F. Kerrison, Vanessa A. Moss, Elaine M. Sadler +1
Recent studies have shown that both 21cm HI absorption and soft X-ray absorption serve as excellent tracers of the dense and dusty gas near the active nucleus of young radio galaxi…
HI absorption at z~0.7 against the lobe of the powerful radio galaxy PKS 0409-75
Elizabeth K. Mahony, James R. Allison, Elaine M. Sadler +15
We present results from a search for the HI 21-cm line in absorption towards 16 bright radio sources with the 6-antenna commissioning array of the Australian Square Kilometre Array…
The gaseous natal environments of GPS and CSS sources with ASKAP -- FLASH
James R. Allison, Elaine M. Sadler, Elizabeth K. Mahony +2
GPS and CSS sources are thought to represent a young and/or confined sub-population of radio-loud active galactic nuclei (AGN) that are yet to evacuate their surrounding ambient in…
The First Large Absorption Survey in HI (FLASH): I. Science Goals and Survey Design
J. R. Allison, E. M. Sadler, A. D. Amaral +27
We describe the scientific goals and survey design of the First Large Absorption Survey in HI (FLASH), a wide field survey for 21-cm line absorption in neutral atomic hydrogen (HI)…
The Rapid ASKAP Continuum Survey Paper II: First Stokes I Source Catalogue Data Release
C. L. Hale, D. McConnell, A. J. M. Thomson +10
The Rapid ASKAP Continuum Survey (RACS) is the first large sky survey using the Australian Square Kilometre Array Pathfinder (ASKAP), covering the sky south of +41 declinat…
Observations of cold extragalactic gas clouds at towards PKS 1610-771
Simon Weng, Elaine M. Sadler, Caroline Foster +7
We present results from MUSE observations of a 21-cm HI absorption system detected with the Australian Square Kilometre Array Pathfinder radio telescope at redshift to…
