Parallel sessions

The advent of new and forthcoming surveys that are both deep and wide is poised to revolutionise our understanding of galaxy evolution, by revealing ‘low-surface-brightness’ (LSB) aspects of galaxies and their environments that are largely invisible in past wide-area datasets. The LSB Universe includes diffuse/dwarf galaxies (which dominate the galaxy number density), merger-induced LSB tidal features (that trace galaxy assembly histories), intra-cluster light (which hosts significant fractions of the baryonic content of clusters), the inter-galactic medium and the faint outskirts of local galaxies.

This regime represents a vast, largely-unexplored discovery space that has become one of the new frontiers in the study of galaxy evolution, especially in light of new and forthcoming surveys like the Hyper Suprime-Cam SSP (HSC-SSP), LSST and EUCLID. The UK community has a particular interest in this field, given its deep involvement in LSST and EUCLID.

This session will (a) discuss emerging techniques and methodologies for the exploitation of deep datasets, (b) present results from observational studies that are exploiting current deep surveys like the DES, Stripe 82, KiDS and HSC-SSP, (c) present the current state-of-the-art in theoretical predictions in the LSB regime, (d) discuss the future promise of surveys e.g. LSST and EUCLID, in which the UK community has a large stake and (e) enable members of the LSB community to make connections that will facilitate collaboration on this topic in the near future.

The proposers are committed to drawing speakers from across the UK LSB community and putting together a programme that is balanced both in terms of gender and career stage.
