WP4 - VO-enabled services to the science community Euro-VO AIDA – First periodic review – 24 April 2009

AIDA WP4 ReportService Activities in support of

provision of VO-enabled services to the science community

Paolo Padovani and Evanthia Hatziminaoglou (ESO)



• Trigger advanced usage of VO capabilities• Obtain a set of well-documented science cases• Gather feedback about the needs of the science

community• Adaptation of VO tools to these needs

In a nutshell: interaction with European astronomers in the area of “science with the VO”

• D4.1 (month 5): First Announcement of Opportunity• D4.2 (month 15): First release of on-line science-oriented

tutorialsPlus work for:• D2.2 (month 9): First “Community Feedback” Workshop• D2.3 (month 13): “Hands-on” Workshop• D2.8 (month 21): Second “Community Feedback” Workshop

WP4 deliverables



• The Euro-VO SAC is a body of 17 “external” astronomers who provide science input to the project (see Francoise Genova’s talk and http://www.euro-vo.org/pub/fc/sac.html)• The SAC met twice in the reporting period: in March (Cambridge, IoA) and December (Strasbourg, CDS)• SAC members were briefed on Euro-VO activities and provided input on Euro-VO Workshops, Research Initiative, etc.• Most SAC members to be renewed in the next couple of months

• Aim: scientific and technical support to teams interested in carrying out astronomical projects utilising VO tools • Announced April 16, deadline June 15 2008• SAC provided input on its content in its March meeting• Publicized through:

Euro-VO mailing list European Astronomical Society newsletter Newsletters of various national astronomical societies

• Main contact person (EH) plus national contact points

WP4 activities: Announcement of Opportunity [D4.1]



• Seven proposals received, meeting with PIs at ESO on Sep. 5 to assess their needs via direct interaction• Three projects supported for 1 yr (until Sep. 15, 2009); scientific ranking provided by SAC:

Is a galaxy’s disk scale-length universal? (PI Fathi [Sweden]; CDS/Astrogrid) Spectral energy distributions of 2XMM-selected AGN (PI Gil-Merino [Spain]; SVO) AGN feedback and quenching of star formation: a multiwavelength approach (PI Lobo [Portugal]; ESO)

• Second call due by June

WP4 activities: Multi-wavelength Astronomy and the VO Workshop [D2.2]



• Goals Identify needs and challenges multi-wavelength astronomy will be facing in the coming

years Identify how the VO can meet them Bring together experts in multi-wavelength astronomy and VO scientists and engineers Overall rationale: scientific needs to drive the technological development; vital to get

input from the astronomical community

• Workshop announcement through Euro-VO mailing list Newsletters of various national astronomical societies Euro-VO SAC AIDA Board




• Workshop Programme included four sessions:– multi-wavelength Astronomy (split in two)– multi-wavelength Astronomy VO tools and standards– Surveys – Putting it all together

• Mix of invited (13) and contributed (15) talks plus 12 posters

• Each session included a > 1 h long round table discussion




• 85 participants (74 non-Euro-VO)• Proceedings will be published by mid-2009• Very relevant feedback for the AIDA project and the VO

in terms of VO tools, services, and metadata

More WP4 related activities



• D2.3 (month 13): “Hands-on” Workshop [DONE] ☺• D4.2 (month 15): First release of on-line science-oriented tutorials [READY]• D4.3 (month 17): Second Announcement of Opportunity• D2.8 (month 21): Second “Community Feedback” Workshop• D4.4 (month 27): Final release of on-line science-oriented tutorials• Plus: continue our interaction with the astronomical community

WP4 plans for next period



• All deliverables done on-time and very successfully• No problems foreseen in completing WP4 work as planned• Announcement of Opportunity, Workshops, and Schools have shown how vital it is to interact with the European astronomical community• FP7 support has proven to be invaluable in organizing all of the above activities• Main message: the European astronomical community (especially the young one) is eager to learn about the Virtual Observatory and use it for its science activities
