Ground-based and space-based VLBI images of 3C 84 at 5 GHz. Left panel: naturally weighted global-VLBI image. The restoring beam size is 1.8 × 0.9 mas at PA = −9° and the rms noise is 0.8 mJy beam−1. We note that the low-intensity emission south of the core region is the well-studied “mini-lobe” related to the 1959 outburst (e.g., Walker et al. 2000; Asada et al. 2006). Middle panel: super-uniformly weighted space-VLBI CLEAN image of the central part of 3C 84. The restoring beam size is 0.60 × 0.30 mas at PA = 23° and the rms noise is 0.9 mJy beam−1. Right panel: regularised maximum likelihood image of the central part of 3C 84 made with EHTIM. The used hyperparameters are MEM = 0, TV1 = 1, TV2 = 1 and L1 = 1. The colour scale in all images has a lightness proportional to the square-root of the pixel intensity.
