First LOFAR observations at very low frequencies of cluster-scale non-thermal emission: the case of Abell 2256

van Weeren, R.J. Röttgering, H.J.A. Rafferty, D.A.

Abell 2256 is one of the best known examples of a galaxy cluster hosting large-scale diffuse radio emission that is unrelated to individual galaxies. It contains both a giant radio halo and a relic, as well as a number of head-tail sources and smaller diffuse steep-spectrum radio sources. The origin of radio halos and relics is still being...

M87 at metre wavelengths: the LOFAR picture

de Gasperin, F. Orru, E. Murgia, M.

Context. M87 is a giant elliptical galaxy located in the centre of the Virgo cluster, which harbours a supermassive black hole of mass 6.4×109 M,whose activity is responsible for the extended (80 kpc) radio lobes that surround the galaxy. The energy generated by matter falling onto the centralblack hole is ejected and transferred to the...
