Recherche / Research
Mes travaux portent sur la dynamique et la physique du gaz neutre (HI) et moléculaire (CO) dans les galaxies spirales, en lien avec les processus de rétroaction stellaire.
My research focuses on the dynamics and physics of neutral (HI) and molecular (CO) gas in spiral galaxies, in connection with stellar feedback processes.
