The MIni-Halos in MIni-Clusters (MIMIC) project: New insights into the origin of mini-halos from a LOFAR, uGMRT, and MeerKAT study of diffuse radio emission in Abell 496 and ZwCl 235

F. Ubertosi, S. Giacintucci, A. Botteon +18

We aim at investigating the presence of diffuse radio emission in low-mass (M M), relaxed galaxy clusters. We present a pilot study for the MIMI…

The LOFAR Two-metre Sky Survey -- V. Second data release

T. W. Shimwell, M. J. Hardcastle, C. Tasse +103

In this data release from the LOFAR Two-metre Sky Survey (LoTSS) we present 120-168MHz images covering 27% of the northern sky. Our coverage is split into two regions centred at ap…

The great Kite in the sky: a LOFAR observation of the radio source in Abell 2626

A. Ignesti, T. Shimwell, G. Brunetti +15

The radio source at the center of the galaxy cluster Abell 2626, also known as the Kite, stands out for its unique morphology composed of four, symmetric arcs. Previous studies hav…

A giant radio bridge connecting two clusters in Abell 1758

A. Botteon, R. J. van Weeren, G. Brunetti +14

Collisions between galaxy clusters dissipate enormous amounts of energy in the intra-cluster medium (ICM) through turbulence and shocks. In the process, Mpc-scale diffuse synchrotr…

LOFAR Observations of X-ray Cavity Systems

L. Bîrzan, D. A. Rafferty, M. Brüggen +8

We present LOFAR observations at 120-168 MHz of 42 systems with possible X-ray cavities in their hot atmosphere, of which 17 are groups or ellipticals, 19 are nearby clusters (z<0.…

The beautiful mess in Abell 2255

A. Botteon, G. Brunetti, R. J. van Weeren +18

We present LOFAR observations of one of the most spectacular objects in the radio sky: Abell 2255. This is a nearby () merging galaxy cluster hosting one of the first r…

LOFAR discovery of a radio halo in the high-redshift galaxy cluster PSZ2 G099.86+58.45

R. Cassano, A. Botteon, G. Di Gennaro +15

In this Letter, we report the discovery of a radio halo in the high-redshift galaxy cluster PSZ2 G099.86+58.45 () with the LOw Frequency ARray (LOFAR) at 120-168 MHz. This…

Evolutionary phases of merging clusters as seen by LOFAR

Amanda Wilber, Marcus Brüggen, Annalisa Bonafede +13

Massive, merging galaxy clusters often host giant, diffuse radio sources that arise from shocks and turbulence; hence, radio observations can be useful for determining the merger s…

First evidence of diffuse ultra-steep-spectrum radio emission surrounding the cool core of a cluster

Federica Savini, Annalisa Bonafede, Marcus Brueggen +14

Diffuse synchrotron radio emission from cosmic-ray electrons is observed at the center of a number of galaxy clusters. These sources can be classified either as giant radio halos,…

New giant radio sources and underluminous radio halos in two galaxy clusters

V. Cuciti, G. Brunetti, R. van Weeren +5

The aim of this work is to analyse the radio properties of the massive and dynamical disturbed clusters Abell 1451 and Zwcl 0634.1+4750, especially focusing on the possible presenc…
