Adaptive Optics Observations of Starburst Galaxiesst and the active nuclei, we can investigate how each affects the other. The proposition that starburst are the results of mergers and that starbursts are progenitors of AGNs can also be tested, by looking for tracers of mergers. Observations of individual galaxies start to answer some of these ques

Cosmology with the Very Large Telescope Interferometer: Using a Space Based Astrometric Reference Frt of absolute distances and proper motions, dispersions of relative proper motions, and images. The ground based interferometers can have huge apertures, which are necessary for faint cosmological targets. But, alone, they are limited to astrometry within the iso-planatic patch, and hence to relativ

1431-2433 ys been ESO‘s aim to operate the VLT in an interferometric mode (VLTI) which allows the coherent combination of stellar light beams col­ lected by the four 8-m telescopes and by several smaller auxiliary telescopes. In December 1993, in response to financial difficulties, the ESO Council de­ cided t

Astrometry with Optical/IR Interferometersver, the instrumental considerations for the two types of measurements are quite different. This paper gives an overview of the instrumental aspects of these two different types of astrometric instruments.
