The Santa Fe topical workshop for 2009 will concentrate on recent developments in cosmology, especially those related to current and expected observational advances, including the cosmic microwave background, large-scale structure, galaxies and clusters, and dark matter and energy/early universe. The format will emphasize discussion with some formal pedagogical review and related talks as appropriate. Generally speaking we would like to reserve the largest fraction of the day for discussion and informal meeting. To encourage this informality and discussion, attendance will be limited to about 80 participants. The last week of the meeting will focus on weak gravitational lensing. More details on this will appear soon.

The workshop will be held at St. John's College, a pleasant and prestigious campus situated in the hills east of downtown Santa Fe. (For help with St. John's information regarding this meeting go to the St. John's Conference Services webpage.) This meeting is part of a continuing series of workshops on cosmology co-organized by staff members at Los Alamos National Laboratory, Fermilab, Lawrence Berkeley National Laboratory, and faculty associated with ACCent. The main sponsors of the 2009 meeting are the Institute of Geophysics and Planetary Physics at Los Alamos National Laboratory, the Kavli Institute for Cosmological Physics at the University of Chicago, the LANL Center for Space Science and Exploration, and the LANL Institute for Advanced Studies.
