MIGHTEE: Are giant radio galaxies more common than we thought?
J. Delhaize, I. Heywood, M. Prescott +31
We report the discovery of two new giant radio galaxies (GRGs) using the MeerKAT International GHz Tiered Extragalactic Exploration (MIGHTEE) survey. Both GRGs were found within a…
MERGHERS Pilot: MeerKAT discovery of diffuse emission in nine massive Sunyaev-Zel'dovich-selected galaxy clusters from ACT
K. Knowles, D. S. Pillay, S. Amodeo +26
The MeerKAT Exploration of Relics, Giant Halos, and Extragalactic Radio Sources (MERGHERS) survey is a planned project to study a large statistical sample of galaxy clusters with t…
The LOFAR Two Meter Sky Survey: Deep Fields, I -- Direction-dependent calibration and imaging
C. Tasse, T. Shimwell, M. J. Hardcastle +29
The Low Frequency Array (LOFAR) is an ideal instrument to conduct deep extragalactic surveys. It has a large field of view and is sensitive to large scale and compact emission. It…
A Wideband Polarization Study of Cygnus A with the JVLA. I: The Observations and Data
M. Lerato Sebokolodi, Rick Perley, Jean Eilek +5
We present results from deep, wideband, high spatial and spectral resolution observations of the nearby luminous radio galaxy Cygnus A with the Jansky Very Large Array. The high su…
MeerKAT's discovery of a radio relic in the bimodal merging cluster A2384
V. Parekh, K. Thorat, R. Kale +12
We present the discovery of a single radio relic located at the edge of the galaxy cluster A2384, using the MeerKAT radio telescope. A2384 is a nearby ( = 0.092), low mass, comp…
Comparison of classical and Bayesian imaging in radio interferometry
Philipp Arras, Hertzog L. Bester, Richard A. Perley +4
CLEAN, the commonly employed imaging algorithm in radio interferometry, suffers from a number of shortcomings: in its basic version it does not have the concept of diffuse flux, an…
