The merging galaxy cluster CIZA J2242.8+5301. The cluster is well-known for its giant radio source, dubbed the 'Sausage', in the North. Multiple radio sources including extended radio emission and tailed radio galaxies are detected with LOFAR observations (in red; Hoang et al. 2017). The cluster also hosts extremely hot gas in the cluster centre, seen with Chandra X-ray observations (in white; Ogrean et al. 2014). Image credits: Duy Hoang/LOFAR Surveys Team
