AMI-LA Observations of the SuperCLASS Super-cluster
C. J. Riseley, K. J. B. Grainge, Y. C. Perrott +21
We present a deep survey of the SuperCLASS super-cluster - a region of sky known to contain five Abell clusters at redshift - performed using the Arcminute Microkelvin I…
Source Finding in Linear Polarization for LOFAR, and SKA Predecessor Surveys, using Faraday Moments
J. S. Farnes, G. Heald, H. Junklewitz +10
The optimal source-finding strategy for linear polarization data is an unsolved problem, with many inhibitive factors imposed by the technically-challenging nature of polarization…
The challenges of low-frequency radio polarimetry: lessons from the Murchison Widefield Array
Emil Lenc, C. S. Anderson, N. Barry +26
We present techniques developed to calibrate and correct Murchison Widefield Array (MWA) low frequency (72-300 MHz) radio observations for polarimetry. The extremely wide field-of-…
On the absence of radio halos in clusters with double relics
A. Bonafede, R. Cassano, M. Brüggen +10
Pairs of radio relics are believed to form during cluster mergers, and are best observed when the merger occurs in the plane of the sky. Mergers can also produce radio halos, throu…
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…
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…
