The aim of this study is to make a bibliometric comparison of the performance of research astronomers in the Netherlands Research School for Astronomy (NOVA) with astronomers elsewhere. This is complementary to similar studies as undertaken by the Center for Science and Technology Studies (CWTS), but has the specific feature of using the NASA Astrophysics Data System (ADS)1 and possibilities of...

Clustering commodity displays into a Tiled Display Wall (TDW) provides a cost-effective way to create an extremely high resolution display, capable of approaching the image sizes now generated by modern astronomical instruments. Many research institutions have constructed TDWs on the basis that they will improve the scientific outcomes of astronomical imagery. We test this concept by presenting...

In fact, this assumption is incorrect and, whilst the Ancient Greek astronomers made huge contributions to astronomy, their knowledge was built upon the solid foundations laid by other great cultures. The Mesopotamian [1] and Zoroastrian astronomers and astrologers, in the Fertile Crescent and the empty deserts of Persia, made many sophisticated observations and devised complex theories to desc...

A review of the study of dark matter and large scale structure of the Universe at Tartu Observatory is given. Tartu astronomers have participated in this development, starting from Ernst Öpik and Grigori Kuzmin, and continuing with the present generation of astronomers. Our goal was to understand better the structure, origin and evolution of the Universe.
