NEW SUPERLUMINAL QUASAR-1633-GAMMA-RAY CONNECTION(382 AND THE BLAZAR)

We report detection of superluminal motion in the core of 4C 38.41, as sociated with the z = 1.814 quasar 1633+382. The dominant nucleus in t he similar to 30 kpc triple morphology of the radio source displays a core-jet structure on the milliarcsecond scale, and a jet component is found moving outward at 6.1 h(-1)c(H-0 = 100 h km s(-1) Mpc(-1), q(0) = 0.5). Quasar 1633+382 is a highly variable object, in both the radi o and the optical wavebands, and in addition an extremely luminous gam ma-ray emitter. It is the ninth gamma-ray blazar displaying superlumin al motion. We point out that all gamma-ray active galactic nuclei (AGN s) which have been observed with VLBI sufficiently well have been foun d to show superluminal expansion. This provides strong support for the commonly accepted hypothesis that AGN gamma-ray emission is produced in a beamed relativistic jet.
