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 discovery of radio emission in MACSJ0717.53745
A. Bonafede, M. Brüggen, D. Rafferty +16
We present results from LOFAR and GMRT observations of the galaxy cluster MACSJ0717.53745. The cluster is undergoing a violent merger involving at least four sub-clusters, a…
LOFAR discovery of an ultra-steep radio halo and giant head-tail radio galaxy in Abell 1132
A. Wilber, M. Brüggen, A. Bonafede +16
LOFAR observations at 144 MHz have revealed large-scale radio sources in the unrelaxed galaxy cluster Abell 1132. The cluster hosts diffuse radio emission on scales of 650 kp…
Evidence for a Toroidal Magnetic-Field Component in 5C4.114 on Kiloparsec Scales
Denise C. Gabuzda, Sebastian Knuettel, Annalisa Bonafede
A monotonic, statistically significant gradient in the observed Faraday Rotation Measure (RM) across the jet of an Active Galactic Nucleus (AGN) reflects a corresponding gradient i…
LOFAR low-band antenna observations of the 3C295 and Bootes fields: source counts and ultra-steep spectrum sources
R. J. van Weeren, W. L. Williams, C. Tasse +98
We present LOFAR Low Band observations of the Bootes and 3C295 fields. Our images made at 34, 46, and 62 MHz reach noise levels of 12, 8, and 5 mJy beam, making them the dee…
Studying Galactic interstellar turbulence through fluctuations in synchrotron emission: First LOFAR Galactic foreground detection
M. Iacobelli, M. Haverkorn, E. Orrú +85
The characteristic outer scale of turbulence and the ratio of the random to ordered components of the magnetic field are key parameters to characterise magnetic turbulence in the i…
M87 at metre wavelengths: the LOFAR picture
F. de Gasperin, E. Orru', M. Murgia +92
M87 is a giant elliptical galaxy located in the centre of the Virgo cluster, which harbours a supermassive black hole of mass 6.4x10^9 M_sun, whose activity is responsible for the…
