Paolo Padovani AVO Work Area 1 (Science) Manager ECF Annual Review, March 15 2004
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)
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)
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
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!
January 2004: AVO First Science ISO LWS Spectrum
January 2004: AVO First Science redshift = 3.046 Ly C IV
January 2004: AVO First Science ~ 40 new obscured QSOs in GOODS CDFS+HDFN x 5 increase
VO Science! • AVO is doing cutting-edge science by exploiting the data beyond “classical” identification limits (R > 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]
What’s 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
VO connecting all European astronomical data centres and providers The Future Grid+Net
Persistent • Data Standards • User support • IVOA link • Distributed • R&D • VO Technologies for new projects and facilities 2005+
EURO-VO Resources - 4 Years • Data Centre Alliance • UK, France, Germany, Italy, Netherlands, Spain, 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
