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)

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

18
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

19
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

20
GLs Task - Observing strategy

• Spectral monitoring (microlensing)
• ToO ? (HME)
• Complementary observations of a well known system
  (extended emission in QSO 2237 0305)

21
GLs Task - Targets

• Multiple imaged QSOs ? best candidates to
  microlesing, candidates to have extended emission
• Q 2237 0305
• Giant Arcs

22
GLs Task - Instruments

• Performances
• Availability in the next (three) years
• Proposals
• Observations

23
GLs Task - Tools

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

24
