Proper Motions of Jets on the Kiloparsec Scale: New Results with HST

Anderson, Jay; Sparks, William B.; Georganopoulos, Markos +7 more

The Hubble Space Telescope recently celebrated 25 years of operation. Some of the first images of extragalactic optical jets were taken by HST in the mid-1990s; with time baselines on the order of 20 years and state-of-the-art astrometry techniques, we are now able to reach accuracies in proper-motion measurements on the order of a tenth of a mill…
