Online radio interferometric imaging: assimilating and discarding visibilities on arrival
Xiaohao Cai, Luke Pratley, Jason D. McEwen
The emerging generation of radio interferometric (RI) telescopes, such as the Square Kilometre Array (SKA), will acquire massive volumes of data and transition radio astronomy to a…
Upper limits on a radio halo in Abell 3667 at 1.4 GHz
M. Johnston-Hollitt, L. Pratley
The presence of a radio halo in the massive, merging cluster Abell 3667 has recently become a focus of debate in the literature following a putative halo detection at 2.4 GHz despi…
LOFAR MSSS: The Scaling Relation between AGN Cavity Power and Radio Luminosity at Low Radio Frequencies
G. Kokotanekov, M. Wise, G. H. Heald +35
We present a new analysis of the widely used relation between cavity power and radio luminosity in clusters of galaxies with evidence for strong AGN feedback. We study the correlat…
PURIFYing real radio interferometric observations
Luke Pratley, Jason D. McEwen, Mayeul d'Avezac +3
Next-generation radio interferometers, such as the Square Kilometre Array (SKA), will revolutionise our understanding of the universe through their unprecedented sensitivity and re…
LOFAR MSSS: Discovery of a 2.56 Mpc giant radio galaxy associated with a disturbed galaxy group
A. O. Clarke, G. Heald, T. Jarrett +40
We report on the discovery in the LOFAR Multifrequency Snapshot Sky Survey (MSSS) of a giant radio galaxy (GRG) with a projected size of Mpc projected on the sky. I…
The w-effect in interferometric imaging: from a fast sparse measurement operator to super-resolution
Arwa Dabbech, Laura Wolz, Luke Pratley +2
Modern radio telescopes, such as the Square Kilometre Array (SKA), will probe the radio sky over large fields-of-view, which results in large w-modulations of the sky image. This e…
