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 new look at old friends. I. Imaging classical radio galaxies with uGMRT and MeerKAT
B. Fanaroff, D. V. Lal, T. Venturi +9
We have undertaken a systematic study of FRI and FRII radio galaxies with the upgraded Giant Metrewave Radio Telescope (uGMRT) and MeerKAT. The main goal is to explore whether the…
Mitigating calibration errors from mutual coupling with time-domain filtering of 21 cm cosmological radio observations
N. Charles, N. S. Kern, R. Pascua +80
The 21 cm transition from neutral Hydrogen promises to be the best observational probe of the Epoch of Reionisation (EoR). This has led to the construction of low-frequency radio i…
The LOFAR Two-metre Sky Survey - II. First data release
T. W. Shimwell, C. Tasse, M. J. Hardcastle +104
The LOFAR Two-metre Sky Survey (LoTSS) is an ongoing sensitive, high-resolution 120-168MHz survey of the entire northern sky for which observations are now 20% complete. We present…
Faceting for direction-dependent spectral deconvolution
C. Tasse, B. Hugo, M. Mirmont +7
The new generation of radio interferometers is characterized by high sensitivity, wide fields of view and large fractional bandwidth. To synthesize the deepest images enabled by th…
The LOFAR Two-metre Sky Survey -- V. Second data release
T. W. Shimwell, M. J. Hardcastle, C. Tasse +103
In this data release from the LOFAR Two-metre Sky Survey (LoTSS) we present 120-168MHz images covering 27% of the northern sky. Our coverage is split into two regions centred at ap…
Hydrodynamical Backflow in X-shaped Radio Galaxy PKS 2014-55
W. D. Cotton, K. Thorat, J. J. Condon +13
We present MeerKAT 1.28 GHz total-intensity, polarization, and spectral-index images covering the giant (projected length ~Mpc) X-shaped radio source PKS~201455…
