Scientific Objectives
We will exploit the depth and the image quality of LSST to derive 1) structural parameters and morphology for up to 4 Billion galaxies 2) search for gravitational lenses taking advantage of model subtracted images; 3) in combination with future spectroscopic surveys, measure the galaxy dark matter content out to z>1, hence deriving the light/dark matter assembly in the last 9 Gyr. For this galaxy sample we foresee relevant spin-off science (AGN variability, time-evolving IMF, scaling relations, large scale flows, etc.) involving a broad group of non-LSST members.
Furthermore, for galaxies not exceeding 200Mpc and with high signal-to-noise ratio, we will measure multi-band surface brightness fluctuations (SBF) 1) to derive accurate distance estimates for the largest extragalactic sample ever collected, with accuracy well within 5-8%, 2) to characterize the properties of the unresolved stellar populations in the galaxies, using SBF color and gradients
