Fitxa persona

My name is Gaëtan Fichet de Clairfontaine, and I am a postdoctoral researcher in astrophysics at the University of Valencia, within Manel Perucho’s group. I earned my PhD in Astrophysics in 2022 at the Paris Observatory, focusing on high-energy phenomena in relativistic jets and their interaction with the surrounding environment.

My research interests include active galactic nuclei (AGN), the dynamics of relativistic jets, jet-star interactions, non-thermal particle acceleration, and multi-messenger astrophysics, with a special emphasis on neutrino and high-energy emission. I combine relativistic magnetohydrodynamic simulations with radiative transfer and theoretical modeling to investigate the observable signatures of dissipative processes in jets.

In addition to my research activities, I am involved in teaching. During the 2025-26 academic year, I was one of the instructors responsible for the outflows module in the Stellar Astrophysics course (Group PT-T, course code 43296).
