## Abstract We present low frequency radio polarimetric observations of the Perseus cluster. The data were taken with the Westerbork Synthesis Radio Telescope (WSRT) between 315–360 MHz. We have discovered faint, extended, highly polarized emission that we associate with the Perseus cluster (de Bru

Abstract
We present the first map of the Perseus Cluster obtained within the Toruń Polarimetric Survey (ToPoS). The maps indicate that there is a large scale polarized radiation located at the periphery of classic radius of this cluster. It seems that an investigation of the magnetic structures we should take into account the contribution from circularly polarized radiation. Few pictures presented here seems to support such a point of view (© 2009 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)

## Abstract NGC 1275, the central galaxy of the Perseus cluster, contains a remarkable cool ISM. This gas is arrayed in a series of filaments extending over 30 kpc with an extension of 70 kpc to the north. These emit substantial cooling line radiation from HII, a hot H~2~ zone, and CO in a cool mol
