Description
Fueled by advances in software, microelectronics, and large optics fabrication,
a new type of sky survey is being designed. In a relentless campaign of 15 second
exposures, the Large Synoptic Survey Telescope will cover the sky to the edge of the
optical universe every three nights, opening a movie-like window on objects that change
or move on rapid timescales: exploding supernovae, potentially hazardous near-Earth
asteroids, etc. The superb images from the LSST will also chart billions of remote
galaxies in 4-D, providing multiple probes of the mysterious Dark Matter and Dark Energy.
Thirty TB of multi-color images per night will be transformed into a new view of our four
dimensional universe. Applied mathematics challenges exist in all phases of the project,
from scheduling optimization to efficient solutions to inverse problems.
