Two-component large-scale radio emission in Abell 2244
M. Cianfaglione, F. De Gasperin, V. Cuciti +9
Context. In recent years, clusters have been observed that host multi-component haloes, both in non-merging and merging systems. The existence of these multi-component haloes sugge…
Galaxy clusters in the LoTSS-DR3: Catalogues and detection pipeline for diffuse radio emission
C. Stuardi, G. Di Gennaro, A. Botteon +19
The third data release of the LOFAR Two-metre Sky Survey provides an unprecedented view of the northern sky at 144 MHz. While compact sources can be efficiently identified with aut…
The LOFAR Two-metre Sky Survey: VII. Third Data Release
T. W. Shimwell, M. J. Hardcastle, C. Tasse +99
We present the third data release of the LOFAR Two-metre Sky Survey (LoTSS-DR3). The survey images cover 88% of the northern sky and were created from 12,950 hrs of data (18.6 PB)…
Weak lensing analysis of A115, A2219 and A2261: Detection of galaxy groups and filaments around clusters
Anirban Dutta, John Peterson, Matteo Cianfaglione +1
We present a weak lensing and multi-wavelength analysis of three galaxy clusters: A115, A2219, and A2261. Weak lensing is performed using shape measurements made in short 60s expos…
Weak Lensing analysis of Abell 2390 using short exposures
A. Dutta, J. R. Peterson, T. Rose +4
We present a weak lensing analysis of the galaxy cluster Abell 2390 at z = 0.23 using second moment shape measurements made in 411 short 60s exposures. The exposures are obtained i…
