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 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…
Constraints on the structure and seasonal variations of Triton's atmosphere from the 5 October 2017 stellar occultation and previous observations
J. Marques Oliveira, B. Sicardy, A. R. Gomes-Júnior +234
A stellar occultation by Neptune's main satellite, Triton, was observed on 5 October 2017 from Europe, North Africa, and the USA. We derived 90 light curves from this event, 42 of…
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…
Fifteen Years of High-Resolution Radio Imaging of Supernova 1987A
B. M. Gaensler, L. Staveley-Smith, R. N. Manchester +3
Supernova 1987A in the Large Magellanic Cloud provides a spectacularly detailed view of the aftermath of a core-collapse explosion. The supernova ejecta initially coasted outward a…
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…
The CRAFT Coherent (CRACO) upgrade I: System Description and Results of the 110-ms Radio Transient Pilot Survey
Z. Wang, K. W. Bannister, V. Gupta +40
We present the first results from a new backend on the Australian Square Kilometre Array Pathfinder, the Commensal Realtime ASKAP Fast Transient COherent (CRACO) upgrade. CRACO rec…
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…
Fourier Modeling of the Radio Torus Surrounding Supernova 1987A
C. -Y. Ng, B. M. Gaensler, L. Staveley-Smith +4
We present detailed Fourier modeling of the radio remnant of Supernova 1987A, using high-resolution 9 GHz and 18 GHz data taken with the Australia Telescope Compact Array over the…
