Breakthrough Galaxy Science expected from the Legacy Survey of Space and Time (LSST)

The Large Synoptic Survey Telescope (LSST) will deliver an unprecedented dataset for studies of galaxy evolution. By imaging the entire southern sky across ultraviolet, optical, and near-infrared bands, it will collect repeated observations over a nominal 10-year survey. After a brief overview of the survey, we will discuss the current status of research in galaxy formation and evolution, as well as the breakthrough science we expect LSST to enable in the coming decade. We will focus on two areas in which LSST will revolutionize the field: the low-surface-brightness regime and the rarest cosmic environments. Both present significant data processing and analysis challenges and require the development of dedicated techniques, some of which are based on artificial intelligence.
