Multi-wavelength images of RX J1532.9+3021. Left panel: High-resolution 144 MHz LOFAR image. Levels:[−3, 3, 9, 20, 40,80]  ×  σ (where σ = 0.13 mJy beam⁻¹). The beam is 8.8″ × 6.2″ and is shown in the bottom left corner of the image. Central panel: Optical Pan-STARRS RGB image with high-resolution LOFAR contours overlaid. Right panel: Chandra X-ray image with overlaid low-resolution LOFAR contours after the subtraction of the central source (Levels=[−3, 3, 7, 15, 50,100]  ×  σ, where σ = 0.24 mJy beam⁻¹ and the beam is 26.6″ × 23.9″). All the panels depict the same region of the sky.
