Seminar Galaxies

This seminar is a weekly meeting to present and discuss the Origin and evolution of galaxies research group’s multiple subjects of study, as well as extragalactic astrophysics and cosmology. The format is either one screening of documents, limited to 30 minutes, or two blackboard presentations, limited to 15 minutes each. All presentations are informal, in order to foster scientific discussions. The sessions last 45 mn, and take place on Thursday at 11:30 am.
