Top left panel: full-resolution LOFAR image contours (white; as shown in the right panel) of Abell 2593, overlaid on an exposure-corrected Chandra image in the 0.5−2.0 keV energy band with a total integration time of 7 ks. Top right panel: 150 MHz LOFAR image (9″ × 6″). The black contours and dashed lines show the (1,2,4,...) × 5 × σ_LOFAR150 and −3 × σ_LOFAR150 levels, respectively, where σ_LOFAR150 = 219 μJy beam⁻¹. Middle left panel: 325 MHz GMRT image (11″ × 7″). The black contours and dashed lines show the (1,2,4,...) × 5 × σ_GMRT325 and −3 × σ_GMRT325 levels, respectively, where σ_GMRT325 = 66 μJy beam⁻¹. Middle right panel: 610 MHz GMRT image (5″ × 4″). The black contours and dashed lines show the (1,2,4,...) × 5 × σ_GMRT610 and −3 × σ_GMRT610 levels, respectively, where σ_GMRT610 = 38 μJy beam⁻¹. Bottom left panel: LOFAR 150 MHz contours (shown in the top left panel) in red overlaid on an SDSS r-band image of Abell 2593. The labelled galaxies (RG1-A and RG2-A) are the possible counterparts for the radio emission of regions A and C. The BCG label indicates the brightest cluster galaxy. Bottom right panel: LOFAR 150 MHz contours (shown in the top right panel) overplotted on the high-resolution (20″ × 20″) spectral index map of Abell 2593.
