Jet structure of 3C 279 revealed by RadioAstron. a: Total intensity (left) and linearly polarized (right) RadioAstron image at 22 GHz obtained on January 15, 2018. Both images show brightness temperature in color scale (afmhot and grayscale, respectively), though the image on the right also shows the recovered electric vector position angles overlaid as ticks. Their length and color are proportional to the level of linearly polarized intensity and fractional polarization, respectively. EHT aligned image from panel b is also displayed in contours over total intensity image. b: The EHT image at 230 GHz obtained in April 2017 at 1:1 scale and aligned to our RadioAstron image -in contours- using their respective pixel with maximum brightness. Contours are equally spaced in 7 levels within the data range. c: The 43 GHz close-in-time image from BEAM-ME program from Feurbary 2018. White ellipses at the bottom-left corners show the convolving beams. Bottom colour bars refer only to information displayed on a.
