We present the first Faraday rotation measure (RM) grid study of an individual low-mass cluster - the Fornax cluster - which is presently undergoing a series of mergers. Exploiting commissioning data for the POlarisation Sky Survey of the Universe's Magnetism (POSSUM) covering a square degree sky area using the Australian Square Kilometre Array Pathfinder (ASKAP), we achieve an RM grid density of RMs per square degree from a 280-MHz band centred at 887 MHz, which is similar to expectations for...[Show more]
