From Centimeter to Millimeter Wavelengths: A High Angular Resolution Study of 3C273
T. P. Krichbaum, A. Witzel, J. A. Zensus
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-ejecti…

A High-Frequency and Multi-Epoch VLBI Study of 3C 273
T. P. Krichbaum, D. A. Graham, A. Witzel +5
We show results from a 7 year VLBI monitoring programme of 3C273 at millimeter wavelengths. We find evidence for component acceleration, motion or rotation of fluid dynamical patte…
