Joint radio-optical views showing that the outer structures shown in Fig. 1 are best interpreted as a pair of RG lobes fed by central jets. On top of DESI Legacy Imaging Surveys DR9 (g, r, z) imagery, we show the LoTSS DR2 at various resolutions through contours at multiples of σ, where σ is the image noise at the relevant resolution. Top and bottom panels: translucent white 60″ contours at 3, 5, 7, 9, 11σ and solid light green 6″ contours at 4, 7, 10, 20, 40σ. Central panel: translucent white 6″ contours at 5, 10, 20, 40, 80σ.
