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…

Galactic Hubs: New Insights and SKA View of AGN Feedback in Galaxy Groups

T. Pasini, M. Brienza, C. J. Riseley

Over the last two decades, significant effort has been devoted to understand the physical processes involved in galaxy evolution. In this context, AGN feedback has emerged as the l…

Single- and double-headed odd radio circles in the LOFAR surveys

F. De Gasperin, M. Brüggen, T. Pasini +7

Deep radio surveys are now producing catalogs with millions of radio sources. Radio sources can have complex morphologies that depend on both the production mechanisms and the loca…

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)…

XGAP with uGMRT I: Old AGN plasma in merging galaxy groups

R. Santra, R. Kale, K. Kolokythas +10

Galaxy groups are affected by outflows from central Active Galactic Nuclei due to the shallower gravitational potential compared to galaxy clusters. The group binding energy is com…

The life of central radio galaxies in clusters: AGN-ICM studies of eRASS1 clusters in the ASKAP fields

Angie Veronica, Thomas H. Reiprich, Florian Pacaud +35

The mechanical feedback from the central AGNs can be crucial for balancing the radiative cooling of the intracluster medium at the cluster centre. We aim to understand the relation…
