Radio fossils, relics, and haloes in Abell 3266: cluster archaeology with ASKAP-EMU and the ATCA
C. J. Riseley, E. Bonnassieux, T. Vernstrom +21
Abell 3266 is a massive and complex merging galaxy cluster that exhibits significant substructure. We present new, highly sensitive radio continuum observations of Abell 3266 perfo…
Independent discovery of a nulling pulsar with unusual sub-pulse drifting properties with the Murchison Widefield Array
Samuel J. McSweeney, N. D. Ramesh Bhat, Nicholas A. Swainston +10
We report the independent discovery of PSR J0027-1956 with the Murchison Widefield Array (MWA) in the ongoing Southern-sky MWA Rapid Two-meter (SMART) pulsar survey. J0027-1956 has…
Improved Sensitivity for Space Domain Awareness Observations with the Murchison Widefield Array
Steve Prabu, Paul J Hancock, Xiang Zhang +4
Our previously reported survey of the Low Earth Orbit (LEO) environment using the Murchison Widefield Array (MWA) detected over 70 unique Resident Space Objects (RSOs) over multipl…
GaLactic and Extragalactic All-sky Murchison Widefield Array survey eXtended (GLEAM-X) I: Survey Description and Initial Data Release
Natasha Hurley-Walker, Timothy J. Galvin, Stefan W. Duchesne +15
We describe a new low-frequency wideband radio survey of the southern sky. Observations covering 72 - 231 MHz and Declinations south of have been performed with the Mur…
Wide-Band Spectral Variability of Peaked Spectrum Sources
K. Ross, N. Hurley-Walker, N. Seymour +3
Characterising spectral variability of radio sources is a technique that offers the ability to determine the astrophysics of the intervening media, source structure, emission and a…
The merging galaxy cluster Abell 3266 at low radio frequencies
S. W. Duchesne, M. Johnston-Hollitt, C. J. Riseley +2
We present new low-frequency (-216 MHz) observations of the complex merging galaxy cluster Abell 3266. These new observations are taken with the Murchison Widefield Array (M…
