Hochauflösende Interferometrie kompakter extragalaktischer Radioquellen
Abstract
Experiments were performed to determine the structures of compact extragalactic radio sources and the dependence of these structures on time. The measurements were made with synthetic-aperture antennas having their component antennas located in different continents. The maximum base line obtained was 8200 km long, or 280 million wavelengths (with lambda equals 2.8 cm); the resolution thus yielded was in the millisecond-of-arc range. Diameters of the measured objects were on the order of 0.1-10 pc. Structures derived were either complex, single, double, or nucleus/halo. The optical type (SEY, EO, or QSO), redshift, and priveleged direction of each of the sources observed are also given.
