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…
The quasar 3C345 at the highest resolution with mm- and space-VLBI
J. Klare, J. A. Zensus, T. P. Krichbaum +2
The quasar 3C345 is one of the best examples of extragalactic jet with superluminal components moving on helical paths. To get better constraints on the jet physics, we have imaged…
