Science Case for Next Generation Optical/Infrared Interferometric Facilities
(the post VLTI era)

23 - 25 August 2004, Liège University,
Colonster Castle, Sart Tilman

37th Liège International Astrophysical Colloquium

Among the planned activities of the Optical Interferometry Network of the European Interferometry Initiatives (EII, OPTICON/FP6), one of the workpackages (WP3) directly aims at developing the vision for a next-generation interferometric facility (post VLTI era) See the link : .

The Network Activity (NA) Committee of EII, presently composed of Eric Bakker, Andrzej Niedzielski, Romain Petrov, Andreas Quirrenbach and Jean Surdej, has proposed to the EII board to first address the science cases for the next generation interferometric facility.

Given the present existing astronomical facilities (ground & space; including existing interferometric facilities), we should wonder what will be the most challenging science areas to be addressed with interferometers in the future (i.e. within 15 years from now). It has been decided to present the science cases during a 3 day scientific workshop entitled "Science Case for Next Generation Optical/Infrared Interferometric Facilities" (the post VLTI era)” to be organized on 23-25 August in Liège.
