COS1: Cosmology and Structure Evolution with Wide-Field Optical and NIR Imaging Surveys

Session Organisers: 

Joe Mohr (Ludwig-Maximilians-Universitat, Munich, Germany), Bob Nichol (Portsmouth), Jochen Weller (LMU, Munich), Richard McMahon (Cambridge)


Wide field imaging surveys have returned tremendous gains for studies of cosmology and the evolution of cosmic structures, and it is clear that we are moving into a world where deep, multiband information is available over every patch of the sky. In this session, our goals are (1) to review the theoretical drivers for these surveys, (2) to hear scientific results from recent and ongoing surveys and (3) to discuss the plans for future surveys.

With the recent selection of Euclid for launch this is a perfect time to bring the community together to discuss the various efforts underway with the goal of increasing collaboration. Moreover, while the scientific drivers for wide field imaging surveys remain unchanged, there is continued rapid development on the techniques that will be most effective in achieving the scientific goals. The new techniques often have implications for survey planning of future missions. Moreover, there is a rich emerging tapestry of theoretical studies to seek an underlying "natural" explanation for the observed cosmic acceleration. An overview of these theoretical developments would provide natural context for the ongoing survey work.

We plan to arrange a combination of overview and highlight talks into two 75-minute sessions. If you are working in this area and would like to give a talk, then please submit an abstract! Note that this session is complementary to the COS2 session on "Future Wide-field Massive Spectroscopic Surveys with 4m Telescopes".
