GGM-filtered images of A2142. Discrete sources were not subtracted and appear as ring structures due to GGM-filtering. Left panel: Chandra X-ray flux image filtered with σ_GGM = 3″. The black cross marks the location of the BCG. The emission visible in the lower left corner is artificial and associated with the ACIS chip boundaries. Right panel: LOFAR HBA radio image filtered with σ_GGM = 12″. The radio emission of H1 follows the spiral pattern of the X-ray cold fronts.
