KAT-7 observations of a mass-selected sample of galaxy clusters
G. Bernardi, T. Venturi, R. Cassano +7
The presence of megaparsec-scale radio halos in galaxy clusters has already been established by many observations over the last two decades. The emerging explanation for the format…
Discovery of a suspected giant radio galaxy with the KAT-7 array
S. Colafrancesco, N. Mhlahlo, T. Jarrett +2
We detect a new suspected giant radio galaxy (GRG) discovered by KAT-7. The GRG core is identified with the WISE source J013313.50-130330.5, an extragalactic source based on its in…
Bayesian Inference for Radio Observations - Going beyond deconvolution
Michelle Lochner, Bruce A. Bassett, Martin Kunz +4
Radio interferometers suffer from the problem of missing information in their data, due to the gaps between the antennas. This results in artifacts, such as bright rings around sou…
KAT-7 detection of radio halo emission in the Triangulum Australis galaxy cluster
Anna M. M. Scaife, Nadeem Oozeer, Francesco de Gasperin +3
We report the presence of high significance diffuse radio emission from the Triangulum Australis cluster using observations made with the KAT-7 telescope and propose that this emis…
Bayesian Inference for Radio Observations
Michelle Lochner, Iniyan Natarajan, Jonathan T. L. Zwart +4
New telescopes like the Square Kilometre Array (SKA) will push into a new sensitivity regime and expose systematics, such as direction-dependent effects, that could previously be i…
