The French Society of Astronomy and Astrophysics (SF2A) organises the French week of Astrophysics in Besançon, from June 29 to July 3. This year, the Swiss Society of Astronomy and Astrophysics (SSAA) will be the special guest of the SF2A. SF2A plenary sessions with several reviews as well as scientific workshops will take place during the week.

The french National Program Cosmology and Galaxies (PNCG) and two societies organise a meeting on July 3, on the topics:
High-resolution numerical simulations and complex physical modelisation
related to galactic, extragalactic, and cosmological studies.

If you wish to attend this meeting and present your work, please register on the SF2A-2009 web site (quote the PNCG/SSAA session in the registration section). The title and abstract must be written in english and are referenced in ADS. Contributions are welcome until June, 12.
