Radio continuum images of A520. The contours are from ±3σ and are spaced by . The image noise is σ = 460, 100, and 26 μJy beam⁻¹ for the LOFAR, GMRT, and VLA images, respectively. The sources are labelled in the VLA image, partly adapting the notation in Vacca et al. (2014). The synthesised beams are shown in the bottom left corners.
