Abstract

The internal structure of jets from active galaxies is explored using the X-ray and radio data. The transverse intensity distributions of X-ray knots in jet are calculated and compared with corresponding intensity distributions for radio knots. It is shown that for selected active galaxies the internal structure of radio knots can be resolved while X-ray knots are almost point-like.

Keywords: extragalactic jets; emission intensity in X-ray and radio range
