High-resolution LOFAR images of A1213. Left: 144 MHz LOFAR-VLBI image of A1213. The image was produced with a restoring beam of 1.5″ × 1.5″, and with an adapted colorscale to enhance the filamentary emission from the tail. Artefacts due to dynamic range issues are still visible in the image. The rms noise is ∼50 μJy beam⁻¹. Right: 144 MHz LOFAR-VLBI image of 4C 29.41, the central radio galaxy of A1213. The image was produced at a resolution of 0.36″ × 0.19″. The largest angular scale for this data is ∼70″, which prevents the detection of the extended tail in the north-east. Contours are from 2σ to highlight the presence of faint emission, with the σ ∼ 45 μJy beam⁻¹ as the rms noise.
