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…
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…
2mm Wavelength VLBI of SiO Masers and AGN
S. Doeleman, R. Phillips, A. Rogers +21
In April 2002 an array of antennas operating at 129GHz successfully detected VLBI fringes on both continuum AGN and SiO maser sources. The 129GHz fringes on maser sources represent…
A High-Frequency and Multi-Epoch VLBI Study of 3C 273
T. P. Krichbaum, D. A. Graham, A. Witzel +5
We show results from a 7 year VLBI monitoring programme of 3C273 at millimeter wavelengths. We find evidence for component acceleration, motion or rotation of fluid dynamical patte…
EVN Observations of GRS1915+105
L. Feretti, G. Giovannini, M. Tordi +12
We obtained EVN observations of the X-ray transient source GRS1915+105 in its radio-loud state. In 2 images obtained before a major flare, the source is resolved, showing two oppos…
