From Centimeter to Millimeter Wavelengths: A High Angular Resolution Study of 3C273
arXiv:astro-ph/0103444
Abstract
We monitored 3C273 with VLBI at 15-86 GHz since 1990. We discuss component trajectories, opacity effects at the jet base, a rotating and perhaps precessing jet, and outburst-ejection relations from Gamma-ray to radio bands.
