The Treble Clef radio phoenix and its old nonthermal filaments

A. Botteon, M. Brienza, K. Rajpurohit +15

By inspecting data from the LOFAR Two-meter Sky Survey (LoTSS), we noticed a peculiar bright and filamentary radio source at low-galactic latitude (). This source…

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)…

A view of the CIZA J2242.8+5301 galaxy cluster at very low radio frequencies

G. Lusetti, M. Brüggen, H. W. Edler +9

The galaxy cluster CIZA J2242.8+5301 is a well-studied merging galaxy cluster that hosts prominent double radio relics including the famous sausage relic, as well as other diffuse…

Discovery of large-scale radio emission enveloping the mini-halo in the most X-ray luminous galaxy cluster RX~J1347.5-1145

D. N. Hoang, M. Brüggen, A. Bonafede +8

Diffuse radio sources, known as mini-halos and halos, are detected at the centres of galaxy clusters. These centralized diffuse sources are typically observed individually, with bo…

Non-thermal emission in galaxy groups at extremely low frequency: the case of A1213

T. Pasini, V. H. Mahatma, M. Brienza +7

Galaxy clusters and groups are the last link in the chain of hierarchical structure formation. Their environments can be significantly affected by outbursts from AGN, especially in…
