The Murchison Widefield Array Phase III upgrade: Sensitivity Doubled, Number of Baselines Quadrupled, Flexibility Enhanced, and EoR Observations Optimised
S. J. Tingay, M. Johnston-Hollitt, R. B. Wayth +32
We describe the latest iteration of upgrades (designated Phase III) to the Murchison Widefield Array (MWA), in the fourth paper in a series that covers the evolution of the telesco…
A Particle Detector Array deployed to the Murchison Widefield Array in the Murchison Radio-astronomy Observatory
J. E. Dickinson, J. D. Bray, D. Kenney +16
We report the design and functionality of the Murchison Widefield Array Particle Detector Array (MWA PDA), an array of eight particle scintillation detectors deployed to Inyarriman…
Experiences of Commercial Supercomputing in Radio Astronomy Data Processing
Ian Kemp, Steven J Tingay, Stuart Midgley +1
The ongoing exponential growth of computational power, and the growth of the commercial High Performance Computing (HPC) industry, has led to a point where ten commercial systems c…
The Growing Impact of Unintended Starlink Broadband Emission on Radio Astronomy in the SKA-Low Frequency Range
Dylan Grigg, Steven Tingay, Marcin Sokolowski
We present the largest survey to date characterising intended and unintended emission from Starlink satellites across the SKA-Low frequency range. This survey analyses ~76 million…
Enhanced detection and identification of satellites using an all-sky multi-frequency survey with prototype SKA-Low stations
Dylan Grigg, Steven Tingay, Steve Prabu +2
With the low Earth orbit environment becoming increasingly populated with artificial satellites, rockets, and debris, it is important to understand the effects they have on radio a…
Processing of GASKAP-HI pilot survey data using a commercial supercomputer
Ian P. Kemp, Nickolas M. Pingel, Rowan Worth +15
Modern radio telescopes generate large amounts of data, with the next generation Very Large Array (ngVLA) and the Square Kilometre Array (SKA) expected to feed up to 292 GB of visi…
