  5. Kazan - 2007

  6. Principal RVO goals • To provide Russian astronomical community with a convenient access to the world astronomical resources • To unite Russian and fSU data, to provide them to the rest of the world and to integrate them into the International Virtual Observatory Kazan - 2007

  7. Other RVO goals • To take part in developing of software, techniques, standards, formats necessary for the establishment of the IVO • To use Russian instrumentation to provide observational data in remote mode when needed • To strengthen education and public applications of world astronomical data • To construct science prototypes Kazan - 2007

  8. RVO goals: I • To provide Russian astronomical community with a convenient access to the world astronomical resources Kazan - 2007

  9. ADS (Astrophysics Data System) – largest astronomical electronic library, including 4 bibliographical databases (astronomy and astrophysics, physics and geophysics, instruments, astronomical preprints). VizieR – most comprehensive database of astronomical catalogues and tables, containing about 4000 catalogues and celestial object dictionary. Mirrors in INASAN INES – archive of about 111000 spectra for about 9600 objects, obtained by IUE space mission. Kazan - 2007

  10. Wide Field Plate DB - 2 mln astronomical wide-field photographic observations stored in 345 archives all over the world (planning). Mirrors in INASAN VALD - collection of atomic line parameters of astronomical interest and tools for selecting subsets of lines for typical astrophysical applications. Hyperleda - an information system for study of the physics and evolution of galaxies, contains about 3 million objects (SAI MSU, SAO RAS). Kazan - 2007

  11. SIMBAD mirror (planning) • The SIMBAD astronomical database provides basic data, cross-identifications, bibliography and measurements for astronomical objects outside the solar system (2 mln stars and 1.5 mln nonstellar objects). Kazan - 2007

  12. RVO goals: II • To unite Russian and fSU data, to provide them to the rest of the world and to integrate them into the International Virtual Observatory Kazan - 2007

  13. Main Russian astronomical organisations Moscow and Moscow region • Sternberg State Astronomical Institute • Institute of Astronomy (INASAN) • Astro Space Centre of Lebebev Physical Institute • Space Research Institute (IKI) • Institute of Terrestrial Magnetism, Ionosphere and Radiowave Propagation (IZMIRAN) St. Petersburg • Main (Pulkovo) Astronomical Observatory • Institute of Applied Astronomy • St. Petersburg State University • Institute of Solar-Terrestrial Physics, Irkutsk • Ural State University, Ekaterinburg • Kazan' State University, Kazan' • Special Astrophysical Observatory (SAO), Nizhnij Arkhyz About 100 astronomical and astronomy-related organisations, departments, institutes Kazan - 2007

  14. Solar Stellar Radio- Mixed System systems astronomy data Sun Stars STP Cosmic rays http://www.inasan.rssi.ru/eng/rvo/rus_res.html Kazan - 2007

  15. Registration of Russian resources • the resources are being registered in the NVO registry • the registry is based on the IVOA document “Resource metadata for the virtual observatory” Kazan - 2007

  16. Digitizing of glass libraries • Russia (and fSU countries) participate in the International project on digitizing of glass libraries of astronomical observatories. • The project is led by Sofia Sky Archive Data Centre. • We have got funding, and we have bought two Epson Expression 1640XL scanners,which allow us to scan plates up to 30x30 cm. Similar scanners are widely used in Bulgaria as well as in Hungary and Germany. Kazan - 2007

  17. Contributors • Institute of Astronomy of the Russian Academy of Sciences • Sternberg Astronomical Institute (Moscow State University) • Main (Pulkovo) Astronomical Observatory • Special Astrophysical Observatory • Crimean Astrophysical Observatory (Ukraine) • Main Astrophysical Observatory (Ukraine) Kazan - 2007

  18. Conclusions Russian Virtual Observatory is merged naturally into the International Virtual Observatory. Russian Virtual Observatory is an open project, any collaboration with other countries and institutes is welcome and required (e. g., participation in federated demos) Kazan - 2007

  20. Kazan - 2007

  21. Astronomical data avalanche • Breakthrough in telescope, detector and computer technology allow astronomical instruments to produce terabytes of images and catalogs. This datasets will cover the sky in different wavebands • In a few years it will be easier to “dial-up” a part of the sky than wait many months to access a telescope Kazan - 2007

  22. Virtual Observatory • Over the past years the concept of the Virtual Observatory has emerged rapidly to address the data management, analysis, distribution and interoperability challenges • The VO is a system in which the vast astronomical archives and databases around the world, together with analysis tools and computational services are linked together into an integrated facility Kazan - 2007

  23. Virtual Observatories • Sixteen VO projects are now funded through national and international programs, and all projects work together under the International Virtual Observatory Alliance to share expertise and develop common standards and infrastructures for data exchange and interoperability • A number of the VO projects are using science prototypes, or demonstration projects to show the user community the benefits of the federated archives, catalogs and computational services Kazan - 2007

  24. What is VO? • We will bring astronomical data from any telescope in the world to any computer, any time, anywhere.Parts of VO are ready now. A grand worldwide scheme: 5-10 years.Less than one Advanced Tactical Fighter aircraft. When it will be ready? What will it cost? Kazan - 2007

  25. Kazan - 2007

  26. RVO goals: III • To take part in developing of software, techniques, standards, formats necessary for the establishment of the IVO Kazan - 2007

  27. IVOA working groups • Data Access Layer • Data Modeling • Grid & Web Services • Resource Metadata / Registry • Standardization process • Knowledge Engineering • Unified Content Descriptors • VO Event • VO Query Language • VOTable / XML Kazan - 2007

  28. RVO goals: VI • To construct science prototypes Kazan - 2007

  29. Catalog cross-correlation services • The identification of objects requires the federation of multiple surveys obtained at different wavelengths and with different observational techniques. Such cross-matching of catalogs was laborious and time consuming • Using VO data access and cross-correlation technologies a search for counterparts in a subset of different catalogues can be carried out in a few minutes Kazan - 2007

  30. Scientific output • A search for brown dwarf candidates in the Sloan and 2MASS catalogs (US NVO prototype) and a search for type 2 QSOs in the VLT, HST and Chandra data (AVO prototype) demonstrated the exciting result of a new object discovery • Information on interstellar extinction may be obtained from modern large photometric surveys data Kazan - 2007
