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…
Proper motion in Cygnus A
U. Bach, T. P. Krichbaum, W. Alef +2
Our recent VLBI observations of the prominent FR II radio galaxy Cygnus A with the EVN and the VLBA reveal a pronounced two-sided jet structure. At 5 GHz, we now have 4 epochs from…
2mm Wavelength VLBI of SiO Masers and AGN
S. Doeleman, R. Phillips, A. Rogers +21
In April 2002 an array of antennas operating at 129GHz successfully detected VLBI fringes on both continuum AGN and SiO maser sources. The 129GHz fringes on maser sources represent…
VLBI observations at 147 GHz: first detection of transatlantic fringes in bright AGN
T. P. Krichbaum, D. A. Graham, W. Alef +21
At 147 GHz (2mm wavelength), we detected three prominent AGN (NRAO150, 3C279, 1633+382) with Very Long Baseline Interferometry (VLBI) with an angular resolution of only 18 micro-ar…
