EVN image of Stokes I (black contours), polarised intensity (colour scale), and EVPA (white bars) of 3C 84 at 22 GHz. The contour levels are at 0.25, 0.5, 1, 2, 4, 8, 16, 32, and 64% of the total intensity peak (S_max = 8.7 Jy beam⁻¹). The lowest contour cutoff is at 5 σ_I, with σ_I = 0.4 Jy beam⁻¹. The convolving beam size is (0.17 × 0.4) mas with a semi-major axis at a position angle of 15.8° north to west (green ellipse in the bottom left corner); the green bar (bottom right) corresponds to a (projected) distance of 4000 R_S (Schwarzschild radius). The cutoff is at 4σ_P, with σ_P = 0.8 Jy beam⁻¹, and only the flux within the boundaries of the Stokes I map is considered. The inset offers a zoomed-in view of the sub-mas region; the red cross corresponds to the position of the jet apex at 22 GHz, as extrapolated in the core-shift analysis presented in Paraschos et al. (2021). For this we assumed that the brightest component in the core region of these observations can be identified with the brightest component in the 86 GHz observations in that paper (see also Paraschos et al. 2023), shifted due to opacity effects. The denoted regions R1 − 4 are defined as R1: jet bend, R2: inner spine, R3: eastern sheath, and R4: western sheath.
