2 N A Walton : AG Consortium Meeting #7 : NeSC : Edinburgh : Dec 14, 2004p2 Printed: 14/12/04 AstroGrid (VO) Key Goals Enable Science by: ● Improving the quality, ease, speed and cost effectiveness of on-line astronomy ● Making comparison and integration of data from diverse sources seamless and transparent ● Removing data analysis barriers to multiwavelength analysis ● Enabling access and manipulation of large data sets

3 N A Walton : AG Consortium Meeting #7 : NeSC : Edinburgh : Dec 14, 2004p3 Printed: 14/12/04 X-ray cluster: Chandra X- ray (Mullis) overlaid on a deep BRI image (Clowe & Luppino). ESO Multiple large image sources: registration & association Source ID from multiplexed spectral data Multi-TB λCDM models, e.g. Millennium Sim Generate Shear Maps c.f. CDM models > DM distribution with redshift Remove stars correlate gals with z Colour-Colour relationships classification in multi-phase space Automatic cluster finding techniques NASA Recap: New & Improved Science: Cosmology

4 N A Walton: PPARC Solar Physics Summer School : MSSL : Sep 15, 2004p4 Printed: 14/12/04 Image from ESO Image + IRIS data Gamma Ray Bursts D. Ducros, ESA Reprocessing of ionospheric STP data change coords from earth to celestial Collate data from multiple telescopes over months - meta data issues Localise GRB alert in minutes – as fade rapidly. SWIFT satellite observes gamma ray burst Compare against SN light curves – bump shows evidence for a SN in the GRB (Price et al, 2002) Interaction with observatory pipe- lines Cross reference multi-λ data – ID pre-cursor and or environment Large computational photometric redshift calcs on multi-λ > gives distance

5 N A Walton: PPARC Solar Physics Summer School : MSSL : Sep 15, 2004p5 Printed: 14/12/04 SOHO/EIT – EUV Yohkoh – Xray NASA: Living With a Star – http://lws.gsfc.nasa.gov What happens to the Earth's magnetosphere during a coronal mass ejection ? Event imaged by space based solar observatory Effect detected later by satellites and ground radar New & Improved Science from VO's: Space Weather

6 N A Walton : AG Consortium Meeting #7 : NeSC : Edinburgh : Dec 14, 2004p6 Printed: 14/12/04 Scoping the VOs ● All major projects – science input — AstroGrid: Science Advisory Group — AVO: Science Working Group — NVO: Science Advisory committee ● Projects define key science goals — Annual demos ● Show early features and use matched to a specific science topic ● Encourage early use — Capability increases year on year — Build towards full working systems ● AstroGrid: deployment of successive 'iteration' releases

7 N A Walton : AG Consortium Meeting #7 : NeSC : Edinburgh : Dec 14, 2004p7 Printed: 14/12/04 Progress against 'The AstroGrid 10' Functionality: end 2004 Functionality: end 2005

8 N A Walton : AG Consortium Meeting #7 : NeSC : Edinburgh : Dec 14, 2004p8 Printed: 14/12/04 AstroGrid Science Advisory Group ● Members represent a wide range of scientific interests – Chair: Andrew Jaffe – Imperial College London ● Set priorities for feature/capability development – Main priorities such as emphasis on ease of data access – Specific capabilities such as solar movie maker – Focus on key data sets ● Propose specific example usage science programmes – e.g. Star formation in the solar neighbourhood (Gould's belt) ● AGSAG represent key UK science input into the wider VO

9 N A Walton: PPARC Solar Physics Summer School : MSSL : Sep 15, 2004p9 Printed: 14/12/04 Optical – IR – Redshifts

10 N A Walton : AG Consortium Meeting #7 : NeSC : Edinburgh : Dec 14, 2004p10 Printed: 14/12/04 Science: The AVO Demo: AG workflows

11 N A Walton : AG Consortium Meeting #7 : NeSC : Edinburgh : Dec 14, 2004p11 Printed: 14/12/04 The AstroGrid Testbed ● Releases deployed on a functional 'Testbed' – Early release on simple resources – Increasing complexity of testbed with each release – Build to link full range of institutional resources ● Current Testbed consists of: – Publishing Registry (Harvesting NVO registry & CDS): Leicester – MySpace servers: Leicester – Applications servers: Manchester. MSSL – Datacenters: Cambridge, Edinburgh, MSSL

12 N A Walton : AG Consortium Meeting #7 : NeSC : Edinburgh : Dec 14, 2004p12 Printed: 14/12/04 AstroGrid Beta Testing Involvement of the end user community ● Beta testing programme to test product releases – Programme includes access to AVO tools ● Beta tester pool composes: – Science Advisory Group – eScience astronomy students – Interested astronomers ● Beta tester programme providing feedback – Importance vital as AstroGrid moves into pre-production use ● Beta testers welcome: http://wiki.astrogrid.org/bin/view/Astrogrid/BetaTesting http://wiki.astrogrid.org/bin/view/Astrogrid/BetaTesting

13 N A Walton : AG Consortium Meeting #7 : NeSC : Edinburgh : Dec 14, 2004p13 Printed: 14/12/04 The Next Steps: Participant in VO Science Demos 2005 ● AstroGrid: Consortium meeting: Today. 14 Dec 2004 — Galaxy distances — Brown dwarf discovery — Solar coronal mass ejections ● Euro-VO: ESAC, Madrid: 25-26 Jan 2005 — Star formation histories — AGB to PN transitions ● A Widening range of capabilities, data, applications — Increasing scientific usefulness ● GOAL: end 2005 – science papers enabled by VO

14 N A Walton : AG Consortium Meeting #7 : NeSC : Edinburgh : Dec 14, 2004p14 Printed: 14/12/04 Next Steps: 2005-2007 ● AstroGrid at the thresh hold of enabling significant science – Prioritisation on automating bulk workflows and data access – Working in partnership to link to additional functionality ● Key science programmes for AstroGrid to 2007 and AstroGrid in the Euro-VO being formulated – Focus on supporting major new (<2007) data flows ● e.g. VISTA, Planck, Herschel, VLT ● Science is a major driver in AG2 and VOTECH (Euro-VO) ● GOAL: 2010 for >90% of all science to be VO enabled
