Murriyang cryogenic phased array feed: spectral-line results and noise-reduction methods
L. Staveley-Smith, S. Barker, R. Berangi +25
Spectral-line results from a new cryogenic phased array feed (cryoPAF) on the Murriyang telescope at Parkes are presented. This array offers a significant improvement in field of v…
Australian Square Kilometre Array Pathfinder: I. System Description
A. W. Hotan, J. D. Bunton, A. P. Chippendale +63
In this paper we describe the system design and capabilities of the Australian Square Kilometre Array Pathfinder (ASKAP) radio telescope at the conclusion of its construction proje…
The Rapid ASKAP Continuum Survey I: Design and First Results
D. McConnell, C. L. Hale, E. Lenc +46
The Rapid ASKAP Continuum Survey (RACS) is the first large-area survey to be conducted with the full 36-antenna Australian Square Kilometre Array Pathfinder (ASKAP) telescope. RACS…
Field sources near the southern-sky calibrator PKS B1934-638: effect on spectral line observations with SKA-MID and its precursors
I. Heywood, E. Lenc, P. Serra +8
Accurate instrumental bandpass corrections are essential for the reliable interpretation of spectral lines from targeted and survey-mode observations with radio interferometers. Ba…
Spectral-line Observations Using a Phased Array Feed on the Parkes Telescope
Tristan Reynolds, Lister Staveley-Smith, Jonghwan Rhee +5
We present first results from pilot observations using a phased array feed (PAF) mounted on the Parkes 64-m radio telescope. The observations presented here cover a frequency range…
Interference Mitigation with a Modified ASKAP Phased Array Feed on the 64 m Parkes Radio Telescope
A. P. Chippendale, G. Hellbourg
We present results from a first attempt to mitigate radio frequency interference in real-time during astronomical measurements with a phased array feed on the 64 m Parkes radio tel…
Observing Pulsars with a Phased Array Feed at the Parkes Telescope
X. Deng, A. P. Chippendale, G. Hobbs +9
During February 2016, CSIRO Astronomy and Space Science and the Max-Planck-Institute for Radio Astronomy installed, commissioned and carried out science observations with a phased…
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…
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…
Wide-field broadband radio imaging with phased array feeds: a pilot multi-epoch continuum survey with ASKAP-BETA
I. Heywood, K. W. Bannister, J. Marvil +45
The Boolardy Engineering Test Array is a 6 x 12 m dish interferometer and the prototype of the Australian Square Kilometre Array Pathfinder (ASKAP), equipped with the first generat…
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…
The Australian Square Kilometre Array Pathfinder: System Architecture and Specifications of the Boolardy Engineering Test Array
