MWA and VLA Observations of Diffuse Radio Lobes in M 87
Linhui Wu, Fu-Guo Xie, Qian Zheng +12
This study investigates the projected, quasi-symmetric -scale diffuse radio lobes surrounding the giant elliptical galaxy M\,87, utilizing well-sampled wideband ($\…
Evolutionary Map of the Universe (EMU): Observations of Filamentary Structures in the Abell S1136 Galaxy Cluster
Peter. J. Macgregor, Ray P. Norris, Andrew O'Brien +17
We present radio observations of the galaxy cluster Abell S1136 at 888 MHz, using the Australian Square Kilometre Array Pathfinder radio telescope, as part of the Evolutionary Map…
GaLactic and Extragalactic All-sky Murchison Widefield Array eXtended (GLEAM-X) survey II: Second Data Release
K. Ross, N. Hurley-Walker, T. J. Galvin +9
We present the second data release for the GaLactic and Extragalactic All-sky Murchison Widefield Array eXtended (GLEAM-X) survey. This data release is an area of 12,892-deg^2 arou…
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…
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…
