Seminar High Energy


This seminar is a weekly meeting to present and discuss the High energy astrophysics and early Universe resesrch group’s multiple subjects of study: high energy astrophysics, sources of gravitational waves, multi-messenger observations, and the distant Universe. The presentations are informal in order to foster scientific discussions. The sessions last 50 mn, and take place on Wednesday at 14:00 am.
