Composite optical (Pan-STARRS), X-ray (Chandra), and radio (LOFAR) image. The LOFAR HBA image of the cluster RBS 797 is shown in red and in contours. The noise is σ_rms = 0.1 mJy beam⁻¹, and the beam is 7.0″ × 4.7″. Contours start at 3σ_rms and increase by a factor 2 each. The Chandra image is displayed in cyan colours, the Pan-STARRS image is a composite g, r, i image. The arcs labelled S3−S6 and the dashed ellipse labelled S​_in refer to the shock fronts detected by Ubertosi et al. (2023). The white arrow points the position of the plume (see Sect. 3).
