A relation between circumnuclear HI, dust, and optical cores in low-power radio galaxies
Ilse M. van Bemmel, Raffaella Morganti, Tom Oosterloo +1
From new observations and literature data we investigate the presence of HI, dust, and optical cores in the central kiloparsec of low-power radio galaxies. The goal of this pilot s…
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…
First LOFAR results on galaxy clusters
C. Ferrari, I. van Bemmel, A. Bonafede +21
Deep radio observations of galaxy clusters have revealed the existence of diffuse radio sources related to the presence of relativistic electrons and weak magnetic fields in the in…
First LOFAR observations at very low frequencies of cluster-scale non-thermal emission: the case of Abell 2256
R. J. van Weeren, H. J. A. Rottgering, D. A. Rafferty +79
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…
