Multiband view of G279+39. Top: Optical g,r,z image from the DESI Legacy Imaging Surveys (Dey et al. 2019). Center: X-ray adaptively smoothed image in the 0.5–2.0 keV band with point sources removed (Döner et al. 2025). Bottom: MeerKAT radio image at 822 MHz with a beam of 9.0″ × 8.0″ (shown in the bottom left corner) and a noise of σ_rms = 4.7 μJy beam⁻¹. The cross and diamond markers indicate the position of the galaxies mentioned in the text. The color bar units are counts s⁻¹ for the X-ray image and Jansky beam⁻¹ for the radio image.
