Multidimensional indexing tools for the virtual observatory
Astronomische Nachrichten, 2007AbstractThe last decade has seen a dramatic change in the way astronomy is carried out. The dawn of the the new microelectronic devices, like CCDs has dramatically extended the amount of observed data. Large, in some cases all sky surveys emerged in almost all the wavelength ranges of the observable spectrum of electromagnetic waves.

A Galactic Model as a Useful Tool for Virtual Observatories
2006Many observational data will be available through Virtual Observatories, but at some wavelengths and in some directions, no data yet exist. Concerning star counts, photometry and classifications, galactic models can be usefully included in VO for statistical inputs.

Investigation of radio sources with the virtual observatory tools: Results and problems
Astronomische Nachrichten, 2013AbstractRadio sources of the RCR catalogue, obtained from observational data of the “Cold” experiment, have been identified, almost completely, with optical objects. For this purpose, we used optical, infrared, and radio sky surveys as well as archive data from the VLA (NRAO) and the 6‐m telescope (SAO).

Federation and Fusion of Astronomical Information: Standards and Tools for the Virtual Observatories
2006We present a review of the current organization of astronomical archives and data centers in terms of data federation. We point the challenges faced, in the VO context, for developing the necessary standards and tools to make data federation and data fusion possible at a general level, covering all potential VO resources.

Most of the projects that aim at detecting extrasolar planets require a careful selection of the central stars as well as an extremely detailed knowledge of their properties and environment. However, gathering information in a wide variety of types and formats from a large number of heterogeneous astronomical data services can be a tedious, very time ...

Virtual Observatory tools for Solar System bodies
2005Research in dynamics and astrometry of objects of the Solar system leads us to provide ephemerides and data useful for the preparation of astrophysical observations from the Earth or from space, and for the analysis of these observations. The advent of the Virtual Observatory project offers new interesting possibilities.

Icarus, 2019
Abstract The Digitized First Byurakan Survey (DFBS) is the digitized version of the Markarian Survey and it is the largest spectroscopic survey by its sky coverage (17, 000 deg2) and by the number of spectra (∼40,000,000). It provides a unique possibility to compare objects between different epochs, as the observations have been carried out in 1965 ...

Time series visualization tools through a Virtual Observatory in geodesy
2013This poster presents the context of the astronomical Virtual Observatory (VO), an ambitious international proposal to provide uniform, convenient access to disparate, geographically dispersed archives of astronomical data from software which runs on the computer on the astronomer's desktop.

The Besançon Model of our Galaxy: a simulation tool towards the Virtual Observatory
2006The Besançon model of our Galaxy is an on-line simulation tool used for various scientific applications. We present here its ongoing implementation in the Virtual Observatory and, as a typical study case of modelisation tool in the VO, we discuss its confrontation with VO standards and tools currently being developed.

The IDIS Joint Research Activity: Tools for a Planetary Virtual Observatory
2009The IDIS Joint Research Activity (JRA-IDIS) of EuroPlaNet RI prepares essential tools implemented as web services allowing the Planetary Science community to interrogate some selected data centres, access and process data, and visualise the results.
