Interconnecting the Virtual Observatory with computational grid infrastructures

Science 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 ...

Bulgarian Grid, Bulgarian Virtual Observatory and Some Astronomical Applications

The development of the Bulgarian GRID, new possibilities for Bulgarian Virtual Observatory and some basic astronomical GRID applications from the published papers and internet are reviewed. Amongst the basic applications are N_body simulations, looking for dark matter, dark energy and neutrino, large scale structure of the Universe, stellar and galaxy evolution, active processes on the Sun, nea...

Bridging the Virtual Observatory and the GRID with the query element

The current generation of Grid infrastructures designed for production activity is strongly computing oriented and tuned on the needs of applications that requires intensive computations. Problems arise when trying to use such Grids to satisfy the sharing of data-oriented and service-oriented resources as happens in the IVOA community. We have designed, developed and implemented a Grid query el...

Virtual Observatory Publishing with DaCHS

The Data Center Helper Suite DaCHS is an integrated publication package for building VO and Web services, supporting the entire workflow from ingestion to data mapping to service definition. It implements all major data discovery, data access, and registry protocols defined by the VO. DaCHS in this sense works as glue between data produced by the data providers and the standard protocols and fo...
