Investigating the intracluster medium viscosity using the tails of GASP jellyfish galaxies
Alessandro Ignesti, Gianfranco Brunetti, Marco Gullieuszik +13
The microphysics of the intracluster medium (ICM) in galaxy clusters is still poorly understood. Observational evidence suggests that the effective viscosity is suppressed by plasm…
LOFAR Deep Fields: Probing the sub-mJy regime of polarized extragalactic sources in ELAIS-N1. I. The catalog
S. Piras, C. Horellou, J. E. Conway +16
The aim of this study is to probe the sub-mJy polarized source population with LOFAR. We present the method used to stack LOFAR polarization datasets, the resulting catalog of pola…
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)…
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…
Observations of a nearby filament of galaxy clusters with the Sardinia Radio Telescope
V. Vacca, M. Murgia, F. Govoni +29
We report the detection of diffuse radio emission which might be connected to a large-scale filament of the cosmic web covering a 8deg x 8deg area in the sky, likely associated wit…
Observations of the galaxy cluster CIZA J2242.8+5301 with the Sardinia Radio Telescope
F. Loi, M. Murgia, F. Govoni +25
We observed the galaxy cluster CIZA J2242.8+5301 with the Sardinia Radio Telescope to provide new constraints on its spectral properties at high frequency. We conducted observation…
