Cosmology with the Large Synoptic Survey Telescope: an Overview

Understand

The Large Synoptic Survey Telescope (LSST) is a high etendue imaging facility that is being constructed atop Cerro Pachon in Northern Chile.

• It is scheduled to begin science operations in 2022.
• With an 8.4m (6.5m effective) aperture, a three-mirror design achieving a seeing-limited 9.6deg^2 field of view, and a 3.2 Gigapixel camera, the LSST has the deep-wide-fast imaging capability to carry out an 18,000deg^2 survey in six passbands (ugrizy) to a coadded depth of r~27.5 over 10 years using 90% of its observational time.
• The remaining 10% will be devoted to deeper and faster time-domain observations and smaller surveys.
