LOFAR : Surveys and Galaxy Clusters

Tim Shimwel

The International LOFAR Telescope offers a transformational increase in radio survey speed compared to existing radio telescopes, as well as opening up the poorly explored low frequency region of the electromagnetic spectrum. For these reasons, an important goal that has driven the development of LOFAR since its inception is to explore the low-frequency radio sky through several surveys, in order to advance our understanding of, amongst many other things, clusters of galaxies. In this talk I outline our latest progress and our future plans for the LOFAR survey of the entire northern sky. I also describe our LOFAR galaxy cluster studies which are beginning to reveal a plethora of diffuse steep spectrum emission that is thought to be associated with turbulence and shocks in the intra cluster medium.
