Hi! I’m Fabian

Portrait of Fabian Schüssler in front of a chalkboard

I am a high-energy astroparticle physicist at IRFU, CEA Paris-Saclay. I study the most violent phenomena in the Universe by combining gamma rays, neutrinos, cosmic rays and gravitational waves, and I build tools to observe them in real time. I lead the development of Astro-COLIBRI and the ANR project MOTS, and I work within the H.E.S.S., CTAO, SVOM and SWGO collaborations.

Find my papers on the publications page (ORCID, INSPIRE), and selected talks and press coverage under Talks & outreach.

On the road

(Astro-)Physicists travel a lot… Here are a few pictures I took during the various travels to observatories, conferences, etc. around the world…
