Compact Intraday Variable Radio Cores: New Observational Approaches
L. Fuhrmann, G. Cimò, T. P. Krichbaum +4
The evidence for refractive interstellar scintillation (RISS) being the main cause for rapid intraday variations (Intraday Variability, IDV) in Quasars and BL Lacs has recently bec…
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…
Understanding Scintillation of Intraday Variables
T. Beckert, L. Fuhrmann, G. Cimo +3
Intraday Variability of compact extragalactic radio sources can be interpreted as quenched scintillation due to turbulent density fluctuations of the nearby ionized interstellar me…
Multi-frequency Study of Intraday Variable Sources
Giuseppe Cimò, L. Fuhrmann, T. P. Krichbaum +4
Intraday variability (IDV) of compact extragalactic radio sources is a complex phenomenon and shows a wavelength dependent mixture of refractive interstellar scintillation (RISS) (…
