LOFAR low resolution, X-ray, and optical overlay of galaxy cluster A1430. The image clearly reveals the halo and large-scale diffuse radio emission in the low density ICM, dubbed as Pillow. The image was obtained using Briggs weighting +0.4 and multiscale clean after the subtraction of sources listed in Table 1. The noise level is σ_rms = 80 μJy beam⁻¹ and the restoring beam is 25″ × 22″ with a position angle of 6°. Contour levels are drawn from 3σ_rms and are spaced by a factor of . Blue colourscale: LOFAR HBA low-resolution image (see Fig. 8 for image properties). Red colourscale: smoothed Chandra X-ray emission in the 0.5−7.0 keV energy band. Background colourscale: SDSS DR15 RGB-colour composite image using the g-, r-, and i-band, respectively.
