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…
Search for the Epoch of Reionisation with HERA: Upper Limits on the Closure Phase Delay Power Spectrum
Pascal M. Keller, Bojan Nikolic, Nithyanandan Thyagarajan +80
Radio interferometers aiming to measure the power spectrum of the redshifted 21 cm line during the Epoch of Reionisation (EoR) need to achieve an unprecedented dynamic range to sep…
On the use of temporal filtering for mitigating galactic synchrotron calibration bias in 21 cm reionization observations
Ntsikelelo Charles, Nicholas Kern, Gianni Bernardi +4
Precision antenna calibration is required for mitigating the impact of foreground contamination in 21 cm cosmological radio surveys. One widely studied source of error is the effec…
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…
Radio footprints of a minor merger in the Shapley Supercluster: From supercluster down to galactic scales
T. Venturi, S. Giacintucci, P. Merluzzi +29
The Shapley Supercluster () contains several tens of gravitationally bound clusters and groups, making it it is an ideal subject for radio studies of…
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…
