Left: the Beaver at 144 MHz, resolution of 0.54″ × 0.40″, rms noise of 27 μJy beam⁻¹. The image was obtained using Briggs weighting, robust = − 0.5, and multiscale. Right: Embryo at 144 MHz, resolution of 0.55″ × 0.40″, rms noise of 40  μJy beam⁻¹. The image was obtained using Briggs weighting, robust = 0.5, and multiscale. Bottom-left panel: zoom-in view of approximately 32 kpc centered on the source. For both images, the restoring beam size is shown in the bottom-left corner.
