Much of modern astronomy relies on data from large sky surveys. The huge amounts of data yielded by the surveys have been a boon for our understanding of the nature of the Universe. Because of the sheer volumes of data involved, however, converting the data into intelligible information requires new data processing and analysis techniques.
IfA researchers have been involved in the development and application of methods for archiving, analysing and modelling data from large sky surveys. Principal areas of interest are establishing a network for archiving large databases for international access and exploitation, and the mapping of dark matter in the Universe directly through gravitational lensing surveys.
