Illuminating the past 8 billion years of cold gas towards two gravitationally lensed quasars
J. R. Allison, V. A. Moss, J. -P. Macquart +15
Using the Boolardy Engineering Test Array of the Australian Square Kilometre Array Pathfinder (ASKAP BETA), we have carried out the first survey for HI and OH absorptio…
The Australian Square Kilometre Array Pathfinder: Performance of the Boolardy Engineering Test Array
D. McConnell, J. R. Allison, K. Bannister +71
We describe the performance of the Boolardy Engineering Test Array (BETA), the prototype for the Australian Square Kilometre Array Pathfinder telescope ASKAP. BETA is the first ape…
The radio spectral energy distribution of infrared-faint radio sources
A. Herzog, R. P. Norris, E. Middelberg +57
Infrared-faint radio sources (IFRS) are a class of radio-loud (RL) active galactic nuclei (AGN) at high redshifts (z > 1.7) that are characterised by their relative infrared faintn…
Testing a modified ASKAP Mark II phased array feed on the 64 m Parkes radio telescope
A. P. Chippendale, R. J. Beresford, X. Deng +4
We present the first installation and characterization of a phased array feed (PAF) on the 64 m Parkes radio telescope. The combined system operates best between 0.8 GHz and 1.74 G…
High-velocity OH megamasers in IRAS 20100-4156: Evidence for a Supermassive Black Hole
L. Harvey-Smith, J. R. Allison, J. A. Green +14
We report the discovery of new, high-velocity narrow-line components of the OH megamaser in IRAS 20100-4156. Results from the Australian Square Kilometre Array Pathfinder (ASKAP)'s…
Recent Developments in Measuring Signal and Noise in Phased Array Feeds at CSIRO
A. P. Chippendale, D. McConnell, K. Bannister +6
We describe recent developments in measuring both signal and noise in phased array feeds for radio astronomy at CSIRO. We introduce new techniques including aperture array noise me…
