A successful search for intervening 21 cm HI absorption in galaxies at 0.4 < z <1.0 with the Australian Square Kilometre Array Pathfinder (ASKAP)
Elaine M. Sadler, Vanessa A. Moss, James R. Allison +6
We have used the Australian Square Kilometre Array Pathfinder (ASKAP) radio telescope to search for intervening 21 cm neutral hydrogen (HI) absorption along the line of sight to 53…
Ionisation of the atomic gas in redshifted radio sources
S. J. Curran, R. W. Hunstead, H. M. Johnston +4
We report the results of a survey for HI 21-cm absorption at z < 0.4 in a new sample of radio sources with the Giant Metrewave Radio Telescope. Of the 11 sources for which there ar…
Further Observational Evidence for a Critical Ionising Luminosity in Active Galaxies
S. J. Curran, R. W. Hunstead, H. M. Johnston +4
We report the results of a survey for HI 21-cm absorption at redshifts of z > 2.6 in a new sample of radio sources with the Green Bank and Giant Metrewave Radio Telescopes. From a…
Galaxy And Mass Assembly (GAMA): The environments of high- and low- excitation radio galaxies
J. H. Y. Ching, S. M. Croom, E. M. Sadler +18
We study the environments of low- and high- excitation radio galaxies (LERGs and HERGs respectively) in the redshift range , using a sample of 399 radio galaxies an…
Optical Spectra of Candidate International Celestial Reference Frame (ICRF) Flat-Spectrum Radio Sources. III
O. Titov, T. Pursimo, H. M. Johnston +4
In extending our spectroscopic program, which targets sources drawn from the International Celestial Reference Frame (ICRF) Catalog, we have obtained spectra for about 160 compact…
Defying jet-gas alignment in two radio galaxies at z~2 with extended light profiles: Similarities to brightest cluster galaxies
C. Collet, N. P. H. Nesvadba, C. De Breuck +7
We report the detection of extended warm ionized gas in two powerful high-redshift radio galaxies, NVSS J210626-314003 at z=2.10 and TXS 2353-003 at z=1.49, that does not appear to…
