Left: Planck y-map overlaid with X-ray (from XMM-Newton, in magenta) and radio (ASKAP/EMU, in black) contours. Black line depicts the 3 × R₂₀₀ of A3391 and black dashed-line points toward the center of A3391. Right: radio+X-ray+optical composite image of the central region of the Northern Clump. The image is generated utilizing ASKAP/EMU image (red color and yellow contour), XMM-Newton image (blue color and white contour), and DECam Sloan g-band image (green color).
