Strong Lenses with LSST: Simulated 10-year Movies of Multiply-Imaged Quasars
Abstract
We use the LSST image simulator to generate realistic 10-year datasets for 100 of the strong galaxy-scale gravitational lenses expected to be measurable with the universal survey data. The 200 mock i-band images have sky brightness and atmospheric seeing drawn from plausible distributions for the Cerro Pachon site, and we use plausibly varying telescope optics and detector response to fully represent the expected image quality. Passing the simulated images through a standard astronomical object detection pipeline gives us our first view of what these rare and valuable objects will look like in the LSST database. We also investigate the recovery of the input lightcurves.
