An ultra-wide bandwidth (704 to 4032 MHz) receiver for the Parkes radio telescope
G. Hobbs, R. N. Manchester, A. Dunning +69
We describe an ultra-wide-bandwidth, low-frequency receiver ("UWL") recently installed on the Parkes radio telescope. The receiver system provides continuous frequency coverage fro…
The Performance and Calibration of the CRAFT Fly's Eye Fast Radio Burst Survey
C. W. James, K. W. Bannister, J. -P. Macquart +13
Since January 2017, the Commensal Real-time ASKAP Fast Transients survey (CRAFT) has been utilising commissioning antennas of the Australian SKA Pathfinder (ASKAP) to survey for fa…
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…
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…
A pilot ASKAP survey of radio transient events in the region around the intermittent pulsar PSR J1107-5907
G. Hobbs, I. Heywood, M. E. Bell +75
We use observations from the Boolardy Engineering Test Array (BETA) of the Australian Square Kilometre Array Pathfinder (ASKAP) telescope to search for transient radio sources in t…
Measured Sensitivity of the First Mark II Phased Array Feed on an ASKAP Antenna
A. P. Chippendale, A. J. Brown, R. J. Beresford +8
This paper presents the measured sensitivity of CSIRO's first Mk. II phased array feed (PAF) on an ASKAP antenna. The Mk. II achieves a minimum system-temperature-over-efficiency $…
Measured Aperture-Array Noise Temperature of the Mark II Phased Array Feed for ASKAP
A. P. Chippendale, A. J. Brown, R. J. Beresford +10
We have measured the aperture-array noise temperature of the first Mk. II phased array feed that CSIRO has built for the Australian Square Kilometre Array Pathfinder telescope. As…
ASKAP HI imaging of the galaxy group IC 1459
P. Serra, B. Koribalski, V. Kilborn +76
We present HI imaging of the galaxy group IC 1459 carried out with six antennas of the Australian SKA Pathfinder equipped with phased-array feeds. We detect and resolve HI in eleve…
Discovery of HI gas in a young radio galaxy at using the Australian Square Kilometre Array Pathfinder
J. R. Allison, E. M. Sadler, V. A. Moss +100
We report the discovery of a new 21-cm HI absorption system using commissioning data from the Boolardy Engineering Test Array of the Australian Square Kilometre Array Pathfinder (A…
The Australian Square Kilometre Array Pathfinder: System Architecture and Specifications of the Boolardy Engineering Test Array
A. W. Hotan, J. D. Bunton, L. Harvey-Smith +98
This paper describes the system architecture of a newly constructed radio telescope - the Boolardy Engineering Test Array, which is a prototype of the Australian Square Kilometre A…
The Australia Telescope 20GHz Survey: Hardware, Observing Strategy, and Scanning Survey Catalog
Paul J. Hancock, Paul Roberts, Michael J. Kesteven +17
The Australia Telescope 20GHz (AT20G) survey is a large area (2π sr), sensitive (40mJy), high frequency (20GHz) survey of the southern sky. The survey was conducted in two parts: a…
The Australia Telescope Compact Array Broadband Backend (CABB)
Warwick E. Wilson, R. H. Ferris, P. Axtens +30
Here we describe the Compact Array Broadband Backend (CABB) and present first results obtained with the upgraded Australia Telescope Compact Array (ATCA). The 16-fold increase in o…
Evolution of the pc-scale structure of PKS 1934-638 revisited: first science with the ASKAP and New Zealand telescopes
A. K Tzioumis, S. J. Tingay, B. Stansby +22
We have studied the archetypal Gigahertz Peaked Spectrum radio galaxy, PKS 1934-638, using the Australian Long Baseline Array, augmented with two new telescopes that greatly improv…
