Virtual Observatory for Astronomers: Where Are We Now?
After several years of intensive technological development Virtual Observatory resources have reached a level of maturity sufficient for their routine scientific exploitation. The Virtual Observatory is starting to be used by astronomers in a transparent way. In this article I will review several research projects making use of the VO at different levels of importance. I will present two projec...
متن کاملAstronomical archives of the future: a Virtual Observatory
Astronomy is entering a new era as multiple, large area, digital sky surveys are in production. The resulting datasets are truly remarkable in their own right; however, a revolutionary step arises in the aggregation of complimentary multi-wavelength surveys (i.e. the cross-identification of a billion sources). Federating these different datasets, however, is an extremely challenging task. With ...
متن کاملScience with Virtual Observatory Tools Astrophysical Virtual Observatory Scientist
The Virtual Observatory is now mature enough to produce cutting-edge science results. The exploitation of astronomical data beyond classical identification limits with interoperable tools for statistical identification of sources has become a reality. I present the discovery of 68 optically faint, obscured (i.e., type 2) active galactic nuclei (AGN) candidates in the two GOODS fields using the ...
متن کاملTowards a National Virtual Observatory
In the near future several new surveys will provide tens of Terabytes of catalogued data for the astronomy community. The archives for these projects are currently being designed. Soon there will be an enormous pressure from the whole astronomical community to integrate these separate archives into a seamlessly interoperating entity. The public access of such amounts of data, and the necessary ...
متن کاملTheory in a Virtual Observatory
During the last couple of years, observers have started to make plans for a Virtual Observatory, as a federation of existing data bases, connected through levels of software that enable rapid searches, correlations, and various forms of data mining. We propose to extend the notion of a Virtual Observatory by adding archives of simulations, together with interactive query and visualization capab...
