Space VLBI polarimetry of IDV sources: Lessons from VSOP and prospects for VSOP2
U. Bach, T. P. Krichbaum, S. Bernhart +5
To locate and image the compact emission regions in quasars, which are closely connected to the phenomenon of IntraDay Variability (IDV), space VLBI observations are of prime impor…
Space-VLBI Polarimetry of the BL Lac Object S5 0716+714: Rapid Polarization Variability in the VLBI core
U. Bach, T. P. Krichbaum, A. Kraus +2
To determine the location of the intra-day variable (IDV) emission region within the jet of the BL Lac object S5 0716+714, a multi-epoch VSOP polarization experiment was performed…
Kinematic Study of the Blazar S5 0716+714
U. Bach, T. P. Krichbaum, E. Ros +5
We present the results of a multi-frequency study of the structural evolution of the VLBI jet in the BL Lac object 0716+714 over the last 10 years. We show VLBI images obtained at…
Gamma-ray to radio activity and ejection of a VLBI component in the jet of the S5-quasar 0836+710
K. Otterbein, T. P. Krichbaum, A. Kraus +4
Broad-band (gamma to radio) variations of the flux density were observed in the first half of 1992 in the luminous high redshift (z = 2.172) quasar S5 0836+710. VLBI monitoring obs…
