  1. The Virtual Observatory Enrique SolanoSpanish VO Principal InvestigatorLAEX-CAB (INTA-CSIC) E. Solano.

  2. E. Solano. Outline • Why do we need Virtual Observatories? • Are they operational yet? • Who is behind them?

  3. E. Solano. Virtual Observatories: The goal • Efficient management of the information available in astronomical archives. • … BUT …accessing to on-line resources through high capacity networks is almost a daily task for most of the astronomers… So, what else is needed?

  4. E. Solano. • 239 000 results • Many unrefereed sources A real-life example:“I want to get all what is known about Vega” Finding the pieces:

  5. E. Solano. A real-life example:“I want to get all what is known about Vega” Finding the pieces (II) • But… is there anything else out there? • Need of astronomical “yellow pages”  VO makes the discovery process more efficient and reliable thanks to Registries.

  6. E. Solano. A real-life example:“I want to get all what is known about Vega” Gathering the pieces • Astronomers need to learn about different user interfaces, access and download procedures. • Tedious, inefficient and painful task.

  7. Without VO n services, n interfaces astronomer archive 1 service 3 archive 2 service 2 archive 3 service 1 survey 1 survey 3 survey 2

  8. With VO n services, “1” interface astronomer archive 1 service 3 archive 2 VO service 2 archive 3 service 1 survey 1 survey 3 survey 2

  9. E. Solano. A real-life example:“I want to get all what is known about Vega” Putting the pieces together

  10. E. Solano. Cerro Pachón. First light 2014 - 5 PB/yr Paranal. Comissioning 2008 - 100 TB/yr Full operation: 2020 - 100 PB/yr The situation is getting worse as astronomical data is growing exponentially Large area surveys: future

  11. E. Solano. The situation is getting worse as astronomical data is growing exponentially

  12. E. Solano. Outline • Why do we need Virtual Observatories? • Are they operational yet? • Who is behind them?: .

  13. E. Solano. Science Tools Stds The VO approach • Agree and build standards. • Uptake of standards by the data services.

  14. Interactive graphical viewer and editor for tabular data. Interactive sky atlas. Science Tools Stds Spectral analysis tools. VO Tools E. Solano.

  15. Alignment, rotation, scale-related issues are tackled in a transparent way for the user. • Remote data as if it was local. VO Tools E. Solano.

  16. Science Tools Stds VO Science E. Solano.

  17. E. Solano. Science that benefits from VO • Multiwavelength astronomy. • Identification of rare/exotic objects

  18. E. Solano. Outline • Why do we need Virtual Observatories? • Are they operational yet? • Who is behind them?

  19. E. Solano. IVOA members

  20. E. Solano. http://svo.laeff.inta.es The Spanish VO • Member of IVOA since June 2004. • Aims: • Coordination of the VO-activities of the Spanish institutes. • Contact-point for the international VO-projects. • Structure: • 9 FTEs at LAEX (the core of the SVO). • Network at national level of (almost) 100 people.

  21. E. Solano. The funding sources • AyA2004-00253, AyA2005-04286 • AyA2005-24102E, AyA2008-02156

  22. E. Solano. SVO: Objectives • Construction of a community of science users: • Scientific Workshops. • Support to VO science programmes • Production of on-line tutorials • This school  • Development of IVOA standards and services • Support to data publishing in the VO • Education and Outreach activities.

  23. E. Solano. Summary • The VO provides new ways to discover, access, and analyze data from astronomical data collections worldwide. • All major data centers provide VO- compatible interfaces to their data. • New and/or more efficient science. • VO Science is already a reality.
