Quasar J1427+3312

The naturally weighted 1.6-GHz VLBI image of J1427+3312 at the frequency of 1.6 GHz (18 cm wavelength). The positive contour levels increase by a factor of v2. The first contours are drawn at -50 and 50 µJy/beam (3 sigma RMS noise). The peak brightness is 460 µJy/beam. Image: JIVE.
