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…
Multi-Epoch Very Long Baseline Interferometric Observations of the Nuclear Starburst Region of NGC 253: Improved modelling of the supernova and star-formation rates
Hayden Rampadarath, John S. Morgan, Emil Lenc +1
The results of multi-epoch observations of the southern starburst galaxy, NGC 253, with the Australian Long Baseline Array (LBA) at 2.3 GHz are presented. As with previous radio in…
Mosaiced wide-field VLBI observations of the Lockman Hole/XMM
Enno Middelberg, Adam Deller, Ray Norris +6
Active Galactic Nuclei (AGN) play a decisive role in galaxy evolution, particularly so when operating in a radiatively inefficient mode, where they launch powerful jets that reshap…
Wide-field VLBI imaging of M31 - first results
Megan K Argo, John Morgan, Emil Lenc +4
One of our closest neighbours, the Andromeda Galaxy (M31) has been the subject of numerous large area studies across the entire spectrum, but so far full-disk radio surveys have be…
Finding AGN with wide-field VLBI observations
Enno Middelberg, Adam Deller, John Morgan +7
VLBI observations are a reliable method to identify AGN, since they require high brightness temperatures for a detection to be made. However, because of the tiny fields of view it…
Wide-field VLBA Observations of the Chandra Deep Field South
Enno Middelberg, Adam Deller, John Morgan +7
Wide-field surveys are a commonly-used method for studying thousands of objects simultaneously, to investigate, e.g., the joint evolution of star-forming galaxies and active galact…
