Parallel sessions

The advent of extra-galactic surveys that are both deep and wide is poised to revolutionise the study of galaxy evolution, by revealing aspects of galaxies and their environments that are invisible in past datasets. These surveys will reveal low-surface-brightness tidal features that encode galaxy merger histories, enable studies of the inter-galactic medium and the faint outskirts of local systems, and truly open up the realm of dwarf galaxies. Low-surface-brightness astronomy, on large statistical samples from deep-wide surveys, is a rapidly-growing topic which has become a priority for the extra-galactic community. This session will (a) discuss emerging techniques and methodologies for the exploitation of deep surveys, (b) present results from studies that are exploiting current datasets like the Stripe 82, the DECAM Legacy Survey (DECaLS) and the Hyper Suprime Cam Survey and (c) discuss the future promise of surveys like LSST and EUCLID, in which the UK community has a large stake.
