  1. Migale Virtual Instrument to study the evolution of galaxies Bulgaria France Russia http://leda.univ-lyon1.fr http://alcor.sao.ru/db/aspid http://giraffe-archive.obspm.fr http://www.sai.msu.su/migale http://draco.skyarchive.org/~hyperleda/

  2. MIGALE • Develop tools (s/w, databases) to study the evolution of galaxies • Mostly (but not only) spectroscopy (gas/stellar populations) - 3D - Multi-dimensional • Support/distribute the science in our laboratories • Supported by iAstro 5-BSCASS, May 2006, Sofia

  3. MIGALE • Support the project in our laboratories • How? Share developments • Why? Avoid duplication of efforts • Data & services for a broad community • Reference data • Archives with added value • Scientific services • Structure of MIGALE • Series of scientific projects • Common s/w structure • Development team 5-BSCASS, May 2006, Sofia

  4. MIGALE • Projects presently supported • DISGAL: Evolution of distant galaxies (Paris-GEPI) • SPIKER: Stellar populations in galaxies (Moscow) • HyperLeda: reference data (Sofia-Lyon) • Giraffe Archive (Paris) • ASPID (SAO-Russia) • Software package • Pleinpot (Lyon-Paris) • Compile data (literature, surveys; catalogues, spectra, images), uniformize • Homogenize, validate • On-the-fly processing & analysis facility • Replicate and distribute through VO 5-BSCASS, May 2006, Sofia

  5. MIGALE • Why VIRTUAL INSTRUMENT? • Use VO (or VO+) data-model internally (take advantage of VO standards within our own tools • Create VO services available for a large community 5-BSCASS, May 2006, Sofia

  6. data processing processing processing processing paper Data2paper v0 data-model (user’s knowledge) 5-BSCASS, May 2006, Sofia

  7. Data2paper v1 Data & data-model processing processing processing processing paper 5-BSCASS, May 2006, Sofia

  8. Data2paper v1 Why Virtual Instrument? Example: Prugniel, Maubon & Simien 2000. ReadMe… The extraction can be re-done customizing some parameters by using a mirror of Hypercat: for example the extraction of L93021HP1_00164.fits may be obtained by downloading the URL: http://www-obs.univ-lyon1.fr/hypercat/fG.cgi?n=11&c=i&o=L93021HP1/00164& z=ffc|spk[2.2,3,2]|wrs|sks|xto[n,2.4]|prj[a,1]|fca|msk[w5575,n1,w5582,n1]& a=mime:application/x-fits 5-BSCASS, May 2006, Sofia

  9. MIGALE Why VIRTUAL INSTRUMENT? • On-the fly processing • Modular architecture: processing/analysing elementary bricks of self-interest 5-BSCASS, May 2006, Sofia

  10. Data2paper v1 Data & data-model processing processing processing processing processing paper 5-BSCASS, May 2006, Sofia

  11. SPIKER • Simultaneous analysis of stellar population & internal kinematics • 3D medium resolution (R=3000) optical spectroscopy of dE galaxies: thesis of Igor Chilingarian • Virtual Instrument based on VO DM 5-BSCASS, May 2006, Sofia

  12. Stellar libraries isochrones 3D obs & cal Stellar libraries Data reduction PEGASE.HR Galactic extinction Resolution matching Adaptive filter (tessellation) Inversion 1D-extraction Field reconstruction SPIKER 5-BSCASS, May 2006, Sofia

  13. MIGALE: actions • Integrate algorithms and databases in VO • Acquire expertise in VO technologies • Improve the VO standards • Science driven use case, when we use them we discover the limits of the DM; we can propose evolution 5-BSCASS, May 2006, Sofia

  14. MIGALE: Challenges • Data-mining from literature, Ingestion • Grid of catalogues • Replication • Homogenization and scientific validation • Analysis in multi-dimensional space • Astronomical services for data-analysis on data & computational grid 5-BSCASS, May 2006, Sofia
