Multi-wavelength differential astrometry of the S5 polar cap sample
J. C. Guirado, J. M. Marcaide, E. Ros +2
We report on the status of our S5 polar cap astrometry program. Since 1997 we have observed all the 13 radio sources of the complete S5 polar cap sample at the wavelengths of 3.6 c…
Radio-optical scrutiny of the central engine in compact AGN
T. G. Arshakian, V. H. Chavushyan, E. Ros +2
We combine Very-Long-Baseline Interferometry (VLBI) data for active galactic nuclei (AGN) available from the Very Large Baseline Array (VLBA) 2 cm imaging survey and opti…
A Multiband Approach to AGN: Radioscopy & Radio Astronomy
M. Kadler, E. Ros, J. Kerp +3
Only in the radio-loud population of active galactic nuclei (AGN) does the production, collimation, and acceleration of powerful relativistic jets take place. We introduce here a c…
Extending and Exploring the 2 cm Survey Sample
E. Ros
We present new results from the VLBA 2 cm Survey, an imaging survey of active galactic nuclei (AGN) at sub-milliarcsecond resolution. We extend the structural variability monitorin…
Combined VLBI- and X-ray Observations of Active Galactic Nuclei
M. Kadler, E. Ros, J. Kerp +2
Compact radio cores in radio-loud active galactic nuclei (AGNs) are classical targets of Very-Long-Baseline interferometric (VLBI) research. Until today little has been known about…
Absolute kinematics of radio source components in the complete S5 polar cap sample
M. A. Perez-Torres, J. M. Marcaide, J. C. Guirado +1
We observed the thirteen extragalactic radio sources of the complete S5 polar cap sample at 15.4 GHz with the Very Long Baseline Array, on 27 July 1999 (1999.57) and 15 June 2000 (…
