The Santa Fe topical workshop for 2003 will concentrate on recent developments in cosmology, especially those related to current and expected observational advances, including the cosmic microwave background (first week), large-scale structure (second week), and dark matter and energy/early universe (third week). 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 wil be limited to about 50 participants.

The workshop will be held at St. John's College, a pleasant and prestigious campus situated in the hills east of downtown Santa Fe. This meeting is part of a continuing series of workshops on cosmology co-organized by the Theoretical Division of Los Alamos National Laboratory and the Theoretical Astrophysics Group at Fermilab. Sponsors include the Center for Cosmological Physics at the University of Chicago, the Theoretical Division at Los Alamos National Laboratory, the Institute for Nuclear and Particle Astrophysics and Cosmology and the Institute of Geophysics and Planetary Physics. The last two are Multi-Campus Research Units (MRUs) of the University of California.
