Merger remnant in TXS 1033+026 - I: and HI 21-cm observations suggest counter-rotating gas

J. N. H. S. Aditya, Hyein Yoon, L. G. Dahmer-Hahn +5

We conducted eMERLIN and Gemini integral field unit (IFU) observations towards TXS 1033+026, a post-merger ultraluminous infrared galaxy, to study the radio continuum and …

A search for HI absorption in distant star-forming galaxies with ASKAP-FLASH - II. Direct observations and stacking of 21 cm line

Sophie L. Eden, Elaine M. Sadler, Kevin A. Pimbblet +5

We present results of a search for associated and intervening HI 21 cm absorption in star-forming galaxies and a control sample of radio galaxies at 0.4 < < 1.0, using ASKAP's…

One sightline, many systems: a FLASH discovery of HI towards scintillating quasar PKS 0405-385

E. F. Kerrison, H. Yoon, E. M. Sadler +15

We report the discovery of an intervening 21\,cm absorption line at z = 0.882 towards the z = 1.284 quasar PKS 0405-385, identified in the First Large Absorption Survey in HI (FLAS…

The First Large Absorption Survey in HI (FLASH): II. Pilot Survey data release and first results

Hyein Yoon, Elaine M. Sadler, Elizabeth K. Mahony +41

The First Large Absorption Survey in HI (FLASH) is a large-area radio survey for neutral hydrogen in the redshift range 0.4<z<1.0, using the 21cm HI absorption line as a probe of c…

WISE data as a photometric redshift indicator for radio AGN

M. Glowacki, J. R. Allison, E. M. Sadler +2

We show that mid-infrared data from the all-sky WISE survey can be used as a robust photometric redshift indicator for powerful radio AGN, in the absence of other spectroscopic or…

A search for HI absorption in nearby radio galaxies using HIPASS

J. R. Allison, E. M. Sadler, A. M. Meekin

Using archival data from the HI Parkes All Sky Survey (HIPASS) we have searched for 21 cm line absorption in 204 nearby radio and star-forming galaxies with continuum flux densitie…

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…

A survey for the missing hydrogen in high redshift radio sources

S. J. Curran, M. T. Whiting, E. M. Sadler +1

Unlike at lower redshift, where there is a 40% detection rate, surveys for 21-cm absorption arising within the hosts of z > 1 radio galaxies and quasars have been remarkably unsucc…

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…
