3. B.Garilli- E3D Kickoff meeting 2-4 July 2002 3D spectroscopy on 8m Telescopes Exploit both VIMOS and FLAMES to study intermediate z (0.5<=z<=1) cluster galaxies Membership and cluster dynamical status: VIMOS (redshift, velocity dispersion) Large field (1 ArcminSq) Low resolution (200) Dynamical properties of cluster members : FLAMES, (line diagnostics, fundamental plane, Tully Fisher) small FOV( 11x7 arcsec) High resolution ( <= 25000)

4. B.Garilli- E3D Kickoff meeting 2-4 July 2002 Task breakdown  Criteria for target selection (confirmed clusters? Different cluster properties?)  Proposal to observe candidates with VIMOS/Ifu  Derive clusters dynamical properties from VIMOS/Ifu data  Compare with simulations  Choose targets for detailed spectroscopical studies  Proposal to observe with FLAMES/Giraffe  Derive galaxy properties in cluster environment from FLAMES/Giraffe data  Compare with simulations  Write papers

5. B.Garilli- E3D Kickoff meeting 2-4 July 2002 Timeline VIMOS possibly available from April 2003 (proposals by Sept 30) FLAMES ? RTN ends in June 2005 IDEAS/CONTRIBUTIONS ARE SOLICITED
