Deep multi-redshift limits on Epoch of Reionisation 21cm Power Spectra from Four Seasons of Murchison Widefield Array Observations
Cathryn M. Trott, C. H. Jordan, S. Midgley +33
We compute the spherically-averaged power spectrum from four seasons of data obtained for the Epoch of Reionisation (EoR) project observed with the Murchison Widefield Array (MWA).…
A study of halo and relic radio emission in merging clusters using the Murchison Widefield Array
L. T. George, K. S. Dwarakanath, M. Johnston-Hollitt +18
We have studied radio haloes and relics in nine merging galaxy clusters using the Murchison Widefield Array (MWA). The images used for this study were obtained from the GaLactic an…
A search for Fast Radio Bursts at low frequencies with Murchison Widefield Array high time resolution imaging
S. J. Tingay, C. M. Trott, R. B. Wayth +26
We present the results of a pilot study search for Fast Radio Bursts (FRBs) using the Murchison Widefield Array (MWA) at low frequencies (139 - 170 MHz). We utilised MWA data obtai…
The Australia Telescope 20GHz (AT20G) Survey: analysis of the extragalactic source sample
Marcella Massardi, Ronald D. Ekers, Tara Murphy +20
The Australia Telescope 20 GHz (AT20G) survey is a blind survey of the whole Southern sky at 20 GHz with follow-up observations at 4.8, 8.6, and 20 GHz carried out with the Austral…
e-VLBI observations of GHz-Peaked Spectrum (GPS) radio sources in nearby galaxies from the AT20G survey
Paul J. Hancock, Steven J. Tingay, Elaine M. Sadler +2
GHz-peaked spectrum (GPS) radio sources are thought to be young objects which later evolve into FR-I and FR-II radio galaxies. We have used the Australia Telescope 20GHz (AT20G) su…
