The interstellar medium in three
dimensions with Gaia

a workshop

Leiden, July 11 - 14, 2011

Obscuration will be a significant issue in the interpretation of data from ESA's Gaia mission. These data provide both an imperative and an opportunity to revolutionise our knowledge of the three-dimensional distribution of the Galaxy's interstellar medium. This revolution is likely in turn to modify profoundly our understanding of how our Galaxy works. The goal of this workshop is to identify the most promising techniques for constructing three-dimensional models of the ISM given both current and upcoming data.

Relevant issues include the dynamics of  both the Galaxy's stellar and gaseous components, techniques for determining the distances of stars, observational probes of the ISM at all wavelengths, the micro structure of the ISM and dust-grain physics.
