  1. Crowded Field Spectroscopy CASTLES

  2. Crowded Field Spectroscopy B 1359 + 154

  3. Long-Slit Mapping • Several exposures are needed to scan the GL system (inefficient) • Different bits of information are recorded under different atmospheric and instrumental conditions (differential atmospheric refraction)

  4. SILFID - ARGUS • Angonin et al., 1990, H 1413+117

  5. SILFID - ARGUS • Vanderriest, 1993, Q 0957+561 • Soucail, 1998, Abell 2218, 370

  6. TIGER • Adam et al, 1989, Q 2237+0305 • Fitte & Adams, 1994 • Q 2237+0305

  7. INTEGRAL - Q 2237+0305

  8. INTEGRAL - Q 2237+0305

  9. INTEGRAL - Q 2237+0305

  10. APPLICATIONS • Study of the compact components and monitoring of possible variations (QSO structure, stellar mass function in the lens) • Study (morphology and redshifts) of the extended emission (QSO host, models of the lens galaxy, high redshift galaxies) • Study of the lens galaxy (absorption and extinction)

  11. OBSERVABLE SYSTEMS

  12. Gravitational Lenses SBS 0909 PG 1115 H 1413 FBQ 0951

  13. Gravitational Lenses Task • Goals • Scientific aims • Observational strategy • Targets • Instruments • Tools (inputs from other tasks...) • Team • Scheduling

  14. GLs Task - Goals • Catalogue ? • Good quality observations of a reduced group of selected objects • Explore innovative techniques of analysis • Diseminate IFS among GL researchers • Profit from the net

  15. GLs Task - Scientific aims • Study of microlensing, specially during an High Magnification Event  study of the quasar unresolved structure • Map the extended emission  model the galaxy mass distribution and study the quasar host galaxy • Gravitational telescope  study high z galaxies

  16. GLs Task - Observing strategy • Spectral monitoring (microlensing) • ToO ? (HME) • Complementary observations of a well known system (extended emission in QSO 2237 + 0305)

  17. GLs Task - Targets • Multiple imaged QSOs  best candidates to microlesing, candidates to have extended emission • Q 2237 + 0305 • Giant Arcs

  18. GLs Task - Instruments • Performances • Availability in the next (three) years • Proposals • Observations

  19. GLs Task - Tools • Data analysis tools (inputs from other tasks) • Scientific tools (inverse mapping, GLs models, etc.)

  20. GLs Task - Team • Euro3D members • IAP: J. Wambsganss ... • CAM: A. Bunker ... • IAC: B. Garcia ... • PAR: ... • DUR: ... • ... • Invited GLs researchers • E. Falco, G. Lewis, L. Goicoechea, ...

  21. GLs Task - SubTasks? • Spectral Monitoring (J. Wambsganss?) • ToO program? • Giant Arcs (A. Bunker?) • Extended Emission (E. Mediavilla?) • Proposals coordinator (B. García?) • Data archive (? + Post-Doc) • ...

  22. GLs Task - Actions • Provisional team definition • Goals and sub-tasks revision • Writing urgent proposals (end of September) • Meeting (November)
