The Australia Telescope Compact Array Broadband Backend (CABB): Description & First Results ⋆
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 observing bandwidth,
Australian SKA Pathfinder: A High-Dynamic Range Wide-Field of View Survey Telescope
As a pathfinder for the SKA, ASKAP will demonstrate field of view enhancement and computing/processing technology as well as the operation of a large-scale radio array in a remote and radio-quiet region of Australia.
The Parkes Pulsar Timing Array Project
Abstract A ‘pulsar timing array’ (PTA), in which observations of a large sample of pulsars spread across the celestial sphere are combined, allows investigation of ‘global’ phenomena such as a
The Detection of an Extremely Bright Fast Radio Burst in a Phased Array Feed Survey
We report the detection of an ultra-bright fast radio burst (FRB) from a modest, 3.4-day pilot survey with the Australian Square Kilometre Array Pathfinder. The survey was conducted in a wide-field
The Australian Square Kilometre Array Pathfinder: System Architecture and Specifications of the Boolardy Engineering Test Array
The Boolardy engineering test array is a prototype of the Australian square kilometre array pathfinder telescope, fitted with prototype signal processing hardware capable of forming at least nine dual-polarisation beams simultaneously, allowing several square degrees to be imaged in a single pointed observation.
ASKAP HI imaging of the galaxy group IC 1459
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 eleven galaxies down to
A fast and accurate scheme for calibration of active phased-array antennas
The international radio-astronomy community is currently making detailed plans for the development of a new radio telescope: the Square Kilometre Array (SKA). This instrument will be a hundred times
The Australian Square Kilometre Array Pathfinder: Performance of the Boolardy Engineering Test Array
The Boolardy Engineering Test Array is the first aperture synthesis radio telescope to use phased array feed technology, giving it the ability to electronically form up to nine dual-polarisation beams.
The 1215-1400 MHz band is important for spectroscopy of H I at high redshift, pulsar work, and SETI. Observations at these frequencies are complicated by pulsed interference from ground-based
