Exploring and the Low Surface Brightness Universe with Deep Imaging

Title: Exploring and the Low Surface Brightness Universe with Deep Imaging

Speaker: Prof. Pierre-Alain Duc

Abstract:

The exploration of the Low Surface Brightness (LSB) Universe currently motivates several surveys across the world, carried out with a number of instruments, and provides observational constrains for numerical simulations.  It impacts multiple scientific fields, including the ISM structure, galaxy formation and evolution and cosmology, and has generated passionate debates, for instance regarding the very existence, nature and  properties of the so called Ultra-Diffuse-Galaxies.  Meanwhile the community  prepares for the exploitation of next generation surveys, including Euclid and LSST. 

I will review the current efforts done by our group in this active field of science and will in particular focus on what deep imaging can tell us about the way galaxies have assembled their mass through mergers.
