Computer power was greatly expanded, to enable research work with various data analysis software packages. Building on Meurs' international standing as an expert in extra-galactic astronomy, notably studying active nuclei, and also with a background in stellar evolution, new research directions have been initiated in Dunsink. Aspects of active galactic nuclei are studied with a variety of observational data. New ways are being developed to describe the large-scale structure discernible in the distribution of galaxies throughout the Universe. Stellar evolution theory is connected with measurements of galaxies in order to assess the status of extragalactic domains that experience remarkably high levels of star formation.
Additional programmes deal for instance with X-ray emission properties of clusters of galaxies.
For over thirty years Dunsink has been involved with instrumentation development.
