Testing the inverse-Compton catastrophe scenario in the intra-day variable blazar S5 0716+71, III. Rapid and correlated flux density variability from radio to sub-mm bands
L. Fuhrmann, T. P. Krichbaum, A. Witzel +22
The BL Lac object S5 0716+71 was observed in a global multi-frequency campaign to search for rapid and correlated flux density variability and signatures of an inverse-Compton (IC)…
A Global 86GHz VLBI Survey of Compact Radio Sources
Sang-Sung Lee, Andrei P. Lobanov, Thomas P. Krichbaum +5
We present results from a large 86GHz global VLBI survey of compact radio sources. The main goal of the survey is to increase by factors of 3--5 the total number of objects accessi…
Towards the Event Horizon - High Resolution VLBI Imaging of Nuclei of Active Galaxies
T. P. Krichbaum, D. A. Graham, A. Witzel +10
We report on new developments in VLBI, with emphasis on experiments performed at the highest frequencies possible to date (so called mm-VLBI). We have observed the nucleus of M 87…
Present and Future Millimeter VLBI Imaging of Jets in AGN: The Case of NRAO 150
I. Agudo, T. P. Krichbaum, U. Bach +8
The Global mm-VLBI Array is at present the most sensitive 3 mm-VLBI interferometer and provides images of up to 40 micro-arcsecond resolution. Using this array, we have monitored t…
The Innermost AGNs with Future mm-VLBI
I. Agudo, T. P. Krichbaum, U. Bach +8
The capabilities of the Global mm-VLBI Array are summarized and demonstrated through actual images from our monitoring of extragalactic radio jets. This sensitive 3mm-VLBI interfer…
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…
