Presentation Transcript

  1. Overview of the L A M Main research axes: • Formation and evolution of galaxies, Cosmology • Interstellar medium • Extra-solar planets Instrumental developments: optics: UV, visible, FIR, Ground based and spatial instrumentation HST, ISO, GALEX, VIMOS,COROT, Herschel, TPF, SNAP, JWST, ELT

  2. Research activities at LAM in relation with MAGPOP Galaxy Evolution, Observational Cosmology ~20 permanent researchers +PhD students & post-docs Involved in MAGPOP: V.Buat, L. Tresse, S. Arnouts, A. Boselli, D Burgarella , J. Iglesias (LAM associate researcher) & M. Treyer Research topics (overview) Physical properties of galaxies: spectral energy distributions, star formation, dust attenuation, environmental effects etc… Statistical studies: number counts, photo-z, morphology, luminosity functions, luminosity densities, correlation functions etc…

  3. Expertise in data analysis • Spectroscopic analyses, diagnostics • Multi-wavelength imaging: UV-opt-FIR • Redshift determinations: Zspec, Zphot • Luminosity functions and densities • Environment, clustering, correlation functions • Modeling: SFR,SFH, dust attenuation • Morphological analysis

  4. MOUs between GALEX & VVDS, GALEX & SWIRE, VVDS & SWIRE, all the data are not public

  5. GALEX: measuring the star formation history from z~0 to 1-2 (in UV) P.I. Chris Martin All Sky Imaging Survey at 1530Å(FUV) and 2315 Å (NUV) 20-21 ABmag Deep Imaging Surveys (few hundreds deg2) 25.5 ABmag Spectroscopic mode: 1300-3000Å Data are becoming public…

  6. GALEX sensitivity

  7. VVDS: VIMOS VLT Deep Survey • PI: O. Le Fevre • Franco-italian consortium • Wide and Deep photometric and I selected spectroscopic surveys • 4 wide fields to Iab=22.5 covering 16 deg2 • 1 deep field to Iab=24 covering 1 deg2 (0<z<5) Low resolution mode : R~230

  8. Current multi- analyses at LAM: GALEX, VVDS (and IRAS & SWIRE) Short presentations • Luminosity functions and densities Laurence Tresse • Deep fields: UV-vis-NIR  Stephane Arnouts • SED analyses UV-FIR  Jorge Iglesias/ Véronique Buat SED modeling  Denis Burgarella/Véronique Buat local universe, environment Alessandro Boselli

  9. Within/in relation with MAGPOP • Post-doc researcher (2 years at LAM+ 1 year at IAP): galex/swire/vvds data. SED analysis and modeling. • SED analyses from low to hi z focusing on UV/FIR emission: SED/modeling • Improving Zphot with new SEDs
