Puzzling large-scale polarization in the galaxy cluster Abell 523
Valentina Vacca, Federica Govoni, Matteo Murgia +13
Large-scale magnetic fields reveal themselves through diffuse synchrotron sources observed in galaxy clusters such as radio halos. Total intensity filaments of these sources have b…
The thermal and non-thermal components within and between galaxy clusters Abell 399 and Abell 401
Federico Radiconi, Valentina Vacca, Elia Battistelli +28
We measure the local correlation between radio emission and Compton- signal across two galaxy clusters, Abell~399 and Abell~401, using maps from the Low-Frequency Array (LOFAR)…
The extended HI halo of NGC 4945 as seen by MeerKAT
Roger Ianjamasimanana, B. S. Koribalski, Gyula I. G. Józsa +20
Observations of the neutral atomic hydrogen (HI) in the nuclear starburst galaxy NGC 4945 with MeerKAT are presented. We find a large amount of halo gas, previously missed by HI ob…
A depolarizing HI tidal tail in the western lobe of Fornax A
Francesca Loi, Paolo Serra, Matteo Murgia +8
Recent MeerKAT neutral hydrogen (HI) observations of Fornax A reveal tidal material intersecting in projection the western lobe of this radio galaxy. We found a spatial coincidence…
Spectral study of the diffuse synchrotron source in the galaxy cluster Abell 523
Valentina Vacca, Timothy Shimwell, Richard A. Perley +26
The galaxy cluster Abell 523 (A523) hosts an extended diffuse synchrotron source historically classified as a radio halo. Its radio power at 1.4 GHz makes it one of the most signif…
