Virtual Observatory

• Innovative, evolving system
• Will allow users to interrogate multiple data
  centres in a seamless and transparent way
• Takes advantage of recent data explosion
• Will allow new science by moving Astronomy
  beyond era of classical identification
• Adoption (and definition) of VO standards and
  protocols within the International Virtual
  Observatory Alliance (IVOA)

3
Virtual Observatory

• Three levels of complexity at data provider
  level
• product availability (show me what you have)
• (raw) product retrieval (give me whatever you
  have)
• science-ready (high-quality) product retrieval
  (give me your nice data and catalogues)

Virtual Observatory in Europe

• AVO Project started November 2001
• Three-year, 5 M, Phase A project, funded by the
  European Commission (Fifth Framework Programme
  FP5) and six organizations ESO, ESA,
  AstroGrid, CNRS (CDS, TERAPIX), University Louis
  Pasteur, JBO
• Manpower 17 FTEs/yr total, 50/50 EC and
  partners, 1 FTE/yr ECF
• Next step EURO-VO, implementation phase (subject
  to EC funding)

5
AVO (Phase A) Goals

• Definition of Science Reference Mission
• Definition of scientific requirements
• Implementation of selected science cases through
  demonstrations
• Science Working Group established two years ago
  to provide scientific advice to AVO Project

6
January 2004 SWG Demo Overview

• Two scenarios
• Extragalactic Obscured (Type 2) Quasars
• Galactic Classification of Young Stellar Objects
  (YSO)
• Multiwavelength, heterogeneous, and complex data
  VLA, CGPS, ISO, 2MASS, USNO, 2.2m/WFI, VLT/FORS,
  HST/ACS, XMM, and Chandra (images, spectra, and
  catalogues)
• Access to any VO-compliant data seamless and
  transparent access to ESA ISO XMM archives and
  ESO data products
• AVO from First Light to First Science!

7
The AVO Prototype

• Evolution of Aladin (CDS)
• Downloadable Java application
• Extensible toolset with plug-ins Astronomy
  Catalogue Extractor (ACE), SpecView, VOPlot, SED
  and cross-match utilities
• New standards Simple Image Access (SIA) and
  Simple Spectral Access (SSA first time ever)
• Prototype but also research tool

VO Science!

• AVO is doing cutting-edge science by exploiting
  the data beyond classical identification limits
  (R gt 24 - 25)
• AVO provides statistical identification of
  sources using multiwavelength information
• VO tools enable astronomers to reach into new
  areas of parameter space with little effort
• AVO should enable everyone to compete with the
  GOODS team (on their data)

• G. Gilmore, SWG meeting, June 2002

12
Whats Next for the European VO?

• Finish the AVO Phase (last demo Jan. 2005)
• We need to move towards EURO-VO
• Work with (not for) the data centres to increase
  interoperability inter-archive tools and
  promote high-quality, science-ready products
  AVO needs these to be truly successful (see last
  demo)!
• Make progress in turning ESO/ST-ECF archive
  VO-compliant
• Funding situation not clear

  ESO, ESA initially 15 Centres
• 2 FTE per centre 100 kEuro/yr upgrades
• Facility Centre
• 4 support scientists (registries, outreach,
  project support ASTROVIRTEL II)
• Technology Centre
• 11 FTE development staff
• TOTAL 15.5 Million Euro
• EC 8 Million Euro

EURO-VO Startup

• EURO-VO component proposals to FP6 in 2003 failed
• Next proposal opportunity in mid 2005
• EURO-VO is too important to be left TOTALLY to
  the EC competitions
• EURO-VO partners will sign MOU in July 2004 to
  start project and bridge the gap between the end
  of AVO (Nov. 2004) and the beginning of EURO-VO
• ESO will contribute 4 new FTEs for 18 months
  starting in July 2004 for EURO-VO DCA and VO-TECH
  work program
• VO-TECH proposal to FP6 design studies submitted
  in March 2004 for 5 Million Euro
