Radio galaxies embedded in the diffuse emission in A1430, namely sources a, b, and c (from left to right). Red contours: LOFAR HBA high-resolution image achieved using Briggs weighting −1.0. The noise level is σ_rms = 65 μJy beam⁻¹, with a restoring beam of 5″ × 4″ and a position angle of −84°. Contour levels start from 3σ_rms and are spaced by a factor of 2. Green contours: VLA B-configuration image. The noise level is σ_rms = 35 μJy beam⁻¹ with a restoring beam of 3″ × 3″ and a position angle of 83°. Contour levels start from 4σ_rms and are spaced by a factor of 2. The corresponding beam sizes are depicted in the lower left corner of the images. Background colourscale: SDSS DR15 RGB-colour composite image using the g-, r-, and i-band, respectively.
