Crowded Field Spectroscopy B 1359 + 154
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)
SILFID - ARGUS • Angonin et al., 1990, H 1413+117
SILFID - ARGUS • Vanderriest, 1993, Q 0957+561 • Soucail, 1998, Abell 2218, 370
TIGER • Adam et al, 1989, Q 2237+0305 • Fitte & Adams, 1994 • Q 2237+0305
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)

Gravitational Lenses Task • Goals • Scientific aims • Observational strategy • Targets • Instruments • Tools (inputs from other tasks...) • Team • Scheduling
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
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
GLs Task - Observing strategy • Spectral monitoring (microlensing) • ToO ? (HME) • Complementary observations of a well known system (extended emission in QSO 2237 + 0305)
GLs Task - Targets • Multiple imaged QSOs best candidates to microlesing, candidates to have extended emission • Q 2237 + 0305 • Giant Arcs
GLs Task - Instruments • Performances • Availability in the next (three) years • Proposals • Observations
GLs Task - Tools • Data analysis tools (inputs from other tasks) • Scientific tools (inverse mapping, GLs models, etc.)
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, ...
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) • ...
GLs Task - Actions • Provisional team definition • Goals and sub-tasks revision • Writing urgent proposals (end of September) • Meeting (November)
