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…

A FLASH HI absorption search in compact sources in the pilot ASKAP interplanetary scintillation field

Paris E. Gordon-Hall, Emily F. Kerrison, Elizabeth K. Mahony +13

In this pilot study, we use data from the First Large Absorption Survey in HI (FLASH) to search for redshifted HI 21cm absorption at towards 157 bright radio sources with…

Tracing Cold Gas in Absorption Across Cosmic Time with the SKA

Elizabeth K. Mahony, Neeraj Gupta, Sergei A. Balashev +12

Observing the 21-cm HI line in absorption provides a powerful means of tracing the cold neutral gas in normal and active galaxies across cosmic time. The frequency coverage and sen…

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 ASKAP-FLASH survey: A first look at the multiwavelength properties and redshift distribution of compact radio sources

W. Roster, E. M. Sadler, E. K. Mahony +15

We present the characterisation, including a photometric redshift (photo-) analysis, of the optical counterparts (CTPs) to over 45 000 bright ( 30 mJy) comp…
