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…
Long-term observations of Uranus and Neptune at 90 GHz with the IRAM 30m telescope - (1985 -- 2005)
C. Kramer, R. Moreno, A. Greve
The planets Uranus and Neptune with small apparent diameters are primary calibration standards. We investigate their variability at ~90 GHz using archived data taken at the IRAM 30…
Mechanical Measurements of the ALMA Prototype Antennas
A. Greve, J. G. Mangum
The specifications of the Atacama Large Millimeter Array (ALMA) have placed stringent requirements on the mechanical performance of its antennas. As part of the evaluation process…
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…
Evaluation of the ALMA Prototype Antennas
Jeffrey G. Mangum, Jacob W. M. Baars, Albert Greve +4
The ALMA North American and European prototype antennas have been evaluated by a variety of measurement systems to quantify the major performance specifications. Nearfield holograp…
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…
