Towards millimeter VLBI
T. P. Krichbaum, U. Bach, D. A. Graham +6
We discuss the present performance and the future perspectives of VLBI in the 3 mm to 0.85 mm observing bands (so called mm-VLBI). The availability of new telescopes and the recent…
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…
Multifrequency Observations of the Blazar 3C 279 in January 2006
WEBT Collaboration, W. Collmar, M. Böttcher +13
We report first results of a multifrequency campaign from radio to hard X-ray energies of the prominent gamma-ray blazar 3C 279, which was organised around an INTEGRAL ToO observat…
The dark nature of GRB 051022 and its host galaxy
A. J. Castro-Tirado, M. Bremer, S. McBreen +17
We present multiwavelength (X-ray/optical/near-infrared/millimetre) observations of GRB 051022 between 2.5 hours and ~1.15 yr after the event. It is the most intense gamma-ray burs…
Extensive multiband study of the X-ray rich GRB 050408. A likely off-axis event with an intense energy injection
A de Ugarte Postigo, T. A. Fatkhullin, G. Johannesson +40
Aims. Understand the shape and implications of the multiband light curve of GRB 050408, an X-ray rich (XRR) burst. Methods. We present a multiband optical light curve, covering the…
A global 86 GHz VLBI survey
S. Lee, A. P. Lobanov, T. P. Krichbaum +5
We present results from a large global VLBI(Very Long Baseline Interferometry) survey of compact radio sources at 86 GHz which started in October 2001. The main goal of the survey…
