About me

My name is Jérémy Fensch. I am an Associate Professor at Ecole Normale Superieure de Lyon and astrophysicist researcher at Centre de Recherche Astrophysique de Lyon.

My research focuses on galaxy evolution, including gas turbulence, galaxy collisions and induced formation of stars, star clusters and tidal dwarf galaxies.

To this purpose, I run and study numerical simulations, using the AMR code RAMSES. I am also involved in observational projects and use data from the VLT and the Hubble Space Telescope.


Main Research Interests

Galactic disk instabilities

Galaxy collisions accross cosmic times

Low surface brightness Universe
