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…
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…
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…
Bandpass calibration of a wideband spectrometer using coherent pulse injection
Nipanjana Patra, Justin D. Bray, Paul Roberts +1
We present a relatively simple time domain method for determining the bandpass response of a system by injecting a nanosecond pulse and capturing the system voltage output. A pulse…
BIGHORNS - Broadband Instrument for Global HydrOgen ReioNisation Signal
M. Sokolowski, S. E. Tremblay, R. B. Wayth +12
The redshifted 21cm line of neutral hydrogen (HI), potentially observable at low radio frequencies (~50-200 MHz), should be a powerful probe of the physical conditions of the inter…
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…
