86 GHz polarimetry of OVV1633+382 after a major mm flare
B. W. Sohn, T. P. Krichbaum, I. Agudo +4
The 18 mag QSO 1633+382 (4C38.41, z=1.807) showed a very pronounced outburst in 2001/2002. With a peak amplitude of more than 9 Jy at 90GHz, this flare was brighter than any known…
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…
Towards the Event Horizon - The Vicinity of AGN at Micro-Arcsecond Resolution
T. P. Krichbaum, D. A. Graham, W. Alef +18
We summarize the present status of VLBI experiments at 3 mm (86 GHz), 2 mm (129-150 GHz) and 1.3 mm (215-230 GHz). We present and discuss a new 3 mm VLBI map of M87 (Virgo A), whic…
Spectral Properties of the Core and the VLBI-Jets of Cygnus A
U. Bach, T. P. Krichbaum, E. Middelberg +4
We present a detailed VLBI study of the spectral properties of the inner core region of the radio galaxy Cygnus A at 5 GHz, 15 GHz, 22 GHz, 43 GHz and 86 GHz. Our observations incl…
Millimetre-VLBI Monitoring of AGN with Sub-milliarcsecond Resolution
A. Pagels, T. P. Krichbaum, D. A. Graham +10
Global millimetre VLBI allows detailed studies of the most central jet regions of AGN with unprecedent spatial resolution of a few 100-1000 Schwartzschild radii to be made. Study o…
