Multi-wavelength images of MACS J2245.0+2637. Upper left panel: High-resolution 144 MHz LOFAR image. Levels:[−3, 3, 5, 9, 15, 30, 60]  ×  σ (where σ = 0.11 mJy beam⁻¹). The beam is 7.0″ × 5.0″ and is shown in the bottom left corner of the image. The insert box shows the image of the central source at 4.5 × 3.2″ resolution obtained with Briggs weighting robust = −1.25 and inner uv-cut. Upper right panel: Optical Pan-STARRS RGB image with high-resolution LOFAR contours overlaid. Lower left panel: Chandra X-ray image smoothed on a scale of 3″ with overlaid low-resolution source-subtracted LOFAR contours (Levels=[−3, 3, 9, 20, 60]  ×  σ, where σ = 0.32 mJy beam⁻¹ and the beam is 35.1″ × 31.7″). Lower right panel: Residual X-ray image after the subtraction of a circular double β-model. All the panels depict the same region of the sky.
