A new approach for constraining the Hubble constant from proper motions of radio jets
Bartosz Lew, Boudewijn F. Roukema, Silke Britzen +1
Withdrawn due to a mistake in jets' Doppler factor modeling. An updated version will appear after revisiting this work.
Kinematic Study of the Blazar 0716+714
U. Bach, T. P. Krichbaum, S. Britzen +3
We determined the kinematics at the jet of 0716+714 from a reanalysis of multi-frequency VLBI data (5, 8.4, 15, 22 GHz) obtained during the last 10 years combined with data from th…
Motion Statistics in the CJ Survey -- The Status in October 2002
R. C. Vermeulen, S. Britzen, G. B. Taylor +4
In the Caltech-Jodrell Survey of bright flat-spectrum radio sources, 3-5 epochs have now been observed for nearly all 293 sources; a uniquely large sample. The derivation of compon…
Is 0716+714 a superluminal blazar?
U. Bach, T. P. Krichbaum, E. Ros +3
We present an analysis of new and old high frequency VLBI data collected during the last 10 years at 5--22 GHz. For the jet components in the mas-VLBI jet, two component identifica…
Radio observations of the -ray blazar 0528+134
M. Pohl, W. Reich, T. P. Krichbaum +10
We report multifrequency observations of the -ray blazar 0528+134 with the Effelsberg 100-m telescope, the IRAM 30-m telescope, and the NRL Green Bank Interferometer. 0528+134 u…
Radio observations of the gamma-ray quasar 0528+134: Superluminal motion and an extreme scattering event
M. Pohl, W. Reich, T. P. Krichbaum +9
We report on multifrequency radio observations made with the Effelsberg 100-m telescope, the IRAM 30-m telescope and the Green Bank Interferometer between 1992 and 1994 of the -…
