PI-Invest Doct Uv Junior
My name is Gaëtan Fichet de Clairfontaine, and I am a postdoctoral researcher in astrophysics at the University of Valencia, within the group of Manel Perucho. I obtained his PhD in Astrophysics in 2022 at the Observatory of Paris, with a focus on high-energy phenomena in relativistic jets and their interaction with the surrounding environment.
My research interests include active galactic nuclei (AGN), relativistic jet dynamics, jet-star interactions, non-thermal particle acceleration, and multi-messenger astrophysics, with particular emphasis on neutrino and high-energy emission. I combine relativistic magnetohydrodynamic simulations with radiative transfer and theoretical modeling to investigate observable signatures of jet dissipation processes.
In addition to my research activity, I am involved in some teaching duties. In the 2025-26 academic year, I was one of the instructors responsible for the outflows module in the course Astrofísica estel·lar (Group PT-T, course code 43296).
