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…
HI absorption at the center of NGC2146
A. Tarchi, A. Greve, A. B. Peck +4
We present 1.4 GHz HI absorption line observations towards the starburst in NGC2146, made with the VLA and MERLIN. The HI gas has a rotating disk/ring structure with column densiti…
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…
The minor axis outflow of NGC 2146
A. Greve, N. Neininger, A. Tarchi +1
X-ray and optical observations have shown that the supernova explosions and stellar winds of the starburst in NGC 2146 produce an outflow of hot material along the minor axis. This…
Radio supernovae, supernova remnants and HII regions in NGC 2146 observed with MERLIN and the VLA
A. Tarchi, N. Neininger, A. Greve +5
We present a high-resolution 5-GHz radio continuum map of the starburst galaxy NGC 2146 made with MERLIN and the VLA, in a search of radio supernovae and supernova remnants expecte…
