"Figure 1 presents our reconstruction of the jet image structure derived from the EHT data using a regularized maximum likelihood method, next to the large-scale source morphology and the similarly edge-brightened morphology of the Messier 87 (M87) jet on comparable gravitational scales. These images are convolved with Gaussian beams set by their respective nominal instrumental resolutions, as per standard practice in radio-interferometric imaging, to suppress possibly spurious fine-scale structures in the image model. The brightness temperatures TT (K) shown are related to flux densities S in jansky (Jy) through the observing wavelength λ, Boltzmann constant kB and angular resolution element Ω as T=λ2(2kBΩ)−1ST=λ2(2kBΩ)−1S. The λ 1.3 mm Cen"
