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…
VLBI studies of FLASH H I 21-cm absorbers -- I
J. N. H. S. Aditya, Elaine M. Sadler, Raffaella Morganti +9
We have conducted VLBA 1.4 GHz (L-band) continuum observations towards twelve sources with HI 21-cm absorption detections at redshift in the pilot surveys of FLASH, an…
Searching for Dark Galaxies with HI detection from the Arecibo Legacy Fast ALFA (ALFALFA) survey
Minseong Kwon, Ho Seong Hwang, Brian R. Kent +3
We present a catalog of 142 dark galaxy candidates in a region covered by the Arecibo Legacy Fast ALFA (ALFALFA) survey. We start with 344 ALFALFA HI sources without optical counte…
ALMACAL XIV: X-Shooter Spectroscopy, Infrared Properties and Radio SEDs of Calibrators
Simon Weng, Elaine M. Sadler, Emily Kerrison +8
The ALMACAL-22 survey includes over 2700 hours of observations of ALMA phase and amplitude calibrators, spanning frequencies from 84 to 950 GHz across bands 3 to 10. In total, 687…
A search for HI absorption in distant star-forming galaxies with ASKAP-FLASH -- I. Selection and analysis of the radio sample
Sophie L. Eden, Elaine M. Sadler, Kevin A. Pimbblet +2
We present and discuss two catalogues of UV-selected (NUV mag) galaxies that lie within a 200 deg area of sky covered by the ASKAP FLASH survey and have an impact para…
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…
The FLASH pilot survey: an HI absorption search against MRC 1-Jy radio sources
J. N. H. S. Aditya, Hyein Yoon, James R. Allison +16
We report an ASKAP search for associated HI 21-cm absorption against bright radio sources from the Molonglo Reference Catalogue (MRC) 1-Jy sample. The search uses pilot survey data…
