A number of scientific topics are addressed with this data-set that are briefly presented in this review: the study of foreground Galactic cirrus at high spatial resolution, telling us about the ISM structure; the characterisation of collisional debris around the galaxies (streams, tails, shells, stellar halos), giving hints on their past merger history; the distribution of dwarf galaxy satellites, including the ultra-diffuse ones, together with their globular cluster population, which are additional tracers of the formation and mass assembly of galaxies. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><a href=\"https:\/\/seafile.unistra.fr\/f\/15db25674efe4d71a3f2\/?dl=1\">Published in IAU S355<\/a>, The real of low surface brightness universe, La Laguna, 2019<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The MATLAS project explores the surroundings of a complete sample of nearby massive early-type galaxies with multi-colour deep optical images obtained at the Canada- France Hawaii Telescope.
