The LSST and Observational Cosmology by David Burke, SLAC

Thursday 6 Mar 2008, 11:00 → 12:00 Europe/Paris

salle 9 (LPSC)

The talk will include a brief overview of elements of obsevational cosmology with emphasis on the technique of weak gravitational lensing. Technical aspects of the proposed Large Synoptic Survey Telescope (LSST) and a summary of the status of the project will be discussed. The LSST will provide an order of magnitude increase in the breadth and depth of all-sky optical surveys. The accumulated 10-year dataset will provide precision 6-band photometry for nearly four billion galaxies, and the survey will detect a quarter million type Ia supernovae per year. Tomographic gravitational lensing measurements will allow the three-dimensional distribution of matter in the universe to be reconstructed continuously from the linear to non-linear regimes of structure formation. The combination of multiple measurements with a single instrument will allow determination of detailed properties of dark energy with excellent precision.
