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 Bruyn & Brentjens 2005). We propose that at least one of these structures is associated with large‐scale structure formation gas inflow from the Perseus‐Pisces supercluster. The extragalactic emission is seen through a polarized Galactic synchrotron foreground screen. The discovery was made possible by a novel rotation measure analysis technique, called Faraday Rotation Measure Synthesis, or RM‐synthesis for short (Brentjens & de Bruyn 2005).
