3C84

VLBA images of 3C84 at multiple wavelengths, on scales of 0.05-5 parsecs, show (contour map A): a central core, an expanding bubble to the south (approaching us); a faint jet connecting the core to the bubble; and a northern (receding) counter-jet, seen through absorption by the accretion disk around the core. The 7mm images of the core show blobs of emission along a line with multiple bends, as if sprayed from a precessing nozzle. Components move at 0.05c, 0.08c, and 0.2c (where c = speed of light) at increasing distances along the jet, as if the blobs are accelerating away from the core. The slow-moving blobs brighten and dim as if a wave of brightening was moving down over them at a velocity of 0.9c.
