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…
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…
An image-based blind search for Fast Radio Bursts in 88 hours of data from the EoR0 Field, with the Murchison Widefield Array
Ian Kemp, Steven Tingay, Stuart Midgley +1
This work is part of ongoing efforts to detect Fast Radio Bursts (FRBs) using the Murchison Widefield Array (MWA) in a spectral window below 300 MHz. We used an image-based method…
An Ultra-High Time Resolution Cosmic Ray Detection Mode for the Murchison Widefield Array
A. Williamson, C. W. James, S. J. Tingay +2
The radio-wavelength detection of extensive air showers (EAS) initiated by cosmic-ray interactions in the Earth's atmosphere is a promising technique for investigating the origin o…
