Observations of IntraDay Variable sources with the Effelsberg and Urumqi Radio Telescopes
N. Marchili, T. P. Krichbaum, X. Liu +7
A sample of classical IntraDay Variable (IDV) and IDV candidate sources has been monitored with the Urumqi 25m telescope and the Effelsberg 100m telescope. Aim of the project is to…
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…
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…
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…
Quasi-Periodic Changes in the Parsec-Scale Jet of 3C345
J. Klare, J. A. Zensus, A. P. Lobanov +3
We have observed the QSO 3C345 with VSOP at 1.6GHz and 5GHz and with the VLBA at 22GHz and 43GHz, with 24 epochs in total, from 1997.40 to 1999.69. This study, combined with previo…
