The Three Dimensional Universe with Gaia - Introduction

Les Rencontres de l'Observatoire 2004 are dedicated to a Symposium on "The Three Dimensional Universe with Gaia". It will take place at the Observatoire de Paris, at the Meudon site, building 18 (LAM), from 4 to 7 October 2004.

The date chosen for this Symposium corresponds to the end of the definition phase of Gaia. The purposes of this Symposium are:

  • to present to the scientific community the design chosen for the mission, the final characteristics and performances, and to update the resulting scientific case
  • to bring to the attention of the scientific community the extraordinary potential of Gaia and to share with the younger generation of scientists the expertise acquired during the preparation phases of the Gaia mission, and during all phases of the Hipparcos mission. Students and young researchers are particularly welcome
  • to organise the next phase of scientific preparation of the mission, in particular the data reduction which constitutes a major challenge with a petabyte of interconnected data which has to be treated in a global and iterative manner, and to prepare for the scientific exploitation of the data.
The Symposium is open to scientists working on the preparation of Gaia and to the large community interested in using the data from the mission.

The invited presentations will be selected by the Scientific Organising Committee and the International Advisory Committee.

A call for contributions and posters, is included in the registration form. The selection will be made by the Committees in June 2004.
