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 )

GLs Task - Targets Multiple imaged QSOs  best candidates to microlesing, candidates to have extended emission Q 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.)
