Superluminal Motions at 500 Mpc: New Results on Nearby AGN Jets with HST
Abstract
I will present results from recent HST observations of several nearby AGN Jets. Using over 20 years of archival data in combination with the most recent deep ACS/WFC imaging, we have found evidence for superluminal motions in optical kpc-scale jets, beyond the only previously reported case of M87. Our observations show that relativistic bulk motions extend to the outermost parts of these jets, and our continuous refinement of astrometric techniques suggests that the reach of Hubble observations, and the constraints on jet models implied by these measurements, may extend beyond 500 Mpc. The presentation will include movies of these jets in which the motions of the plasma can be seen by eye.
