The Doctoral School of Astronomy-Astrophysics of Paris Area (ED 127) is the only thematic doctoral school in France, in the field of astronomy and astrophysics. The school is supported by four universities or Institutes : the Paris Observatory (carrier), Université Paris-Sud (P11), Université Paris Diderot (P7) and UPMC (P6).
Since 2008, the Doctoral School organizes a biennial international school in the field of observational astronomy, intended for PhD students and postdocs. The third edition of this school will be held in March 2013. The previous two had been very successful and received about 40 participants each, representing more than fifteen different nationalities. This is the third edition of a school with the goal to train young researchers, PhD students and postdocs, regardless of nationality, to the scientific exploitation of two recently launched European space missions, Planck and Herschel. The first results obtained by these two satellites, the most successful ever launched in their respective fields, are reshaping the landscape in many areas of astrophysics (cosmology, galaxies and large structures, star formation, interstellar medium, the solar system) and there is some urgency to introduce the concepts and specific methods of exploitation of their data to future researchers. The school last one week and will follow the organization of the two schools previously held by the ED 127, a scheme that has proved itself and was appreciated by participants. The morning is devoted to lectures given by leading researchers, from around the world, and the afternoon is devoted to practical work in pairs around computers. These includes manipulating data from each satellite, a familiarization with the software to access, treatment and data analysis, using tools developed by space agencies and consortia of the two scientific missions. The astrophysical interpretation will also be addressed by numerical models developed by the community. We will offer to students the opportunity to explore the complete chain that goes from theory to the analysis of astrophysical observations. From a practical standpoint, the whole school will be held at the International Centre of Pedagogical Studies (CIEP) in Sèvres, a center able to accommodate all participants in half-board at a reasonable cost and providing modern teaching facilities. The morning will be devoted to lectures and the afternoon, students will use the computer workstations in special rooms. Students will be invited to present a poster on a topic that motivates them particularly. A laboratory visit will take place during a half day. One feature of this school is to target a wide international audience, particularly to developing countries. Accordingly, we maintain a low registration fee, thanks to a call for funding by several partners.
