Migale: Virtual Instrument for Galaxy Evolution Studies

Migale develops tools and databases for studying the evolution of galaxies, focusing on spectroscopy and multi-dimensional analysis. Projects supported include DISGAL, SPIKER, HyperLeda, Giraffe Archive, and ASPID. The virtual instrument aims to make data processing and analysis more efficient by utilizing VO standards, creating services accessible to a wide community.

  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
