Image Details
Caption: Figure 3.
A 8.6 GHz VLBI image of 1508+572 obtained with a five-element global network of radio telescopes (Sv, Zc, Bd, Yb, Sh) on 2019 July 13 (project code RUA032). The peak brightness is 341 mJy beam−1, the lowest contours are at 0.812 mJy beam−1, the positive contour levels increase by a factor of 2. The elliptical Gaussian restoring beam indicated in the lower left corner has major and minor axes 0.837 mas and 0.707 mas (half-power beamwidth), respectively, with a major axis position angle −0.°4, measured from north through east. The mas-scale structure of the source is dominated by the bright core; a jet component is seen toward south.
