About 80% of the total baryonic matter of the Universe is in the form of a very hot X-ray emitting plasma, which fills the very large gravitational well in clusters of galaxies. This intra-cluster medium (ICM) is rich in heavy elements (O, Mg, Si, S, Ca, Fe, Ni,...), which do not have a primordial origin. Instead, these atoms have been created by billions of supernovae within cluster galaxies since a major star forming epoch, then spread out and accumulated over cosmic time into the ICM. Using X-ray observatories, I study these metal abundances in the ICM, in order to understand their precise supernovae origins, as well as their transport mechanisms.

Here are some of my scripts and routines you may find useful...
Fits a set of intra-cluster abundances with a combination of supernova yield models. Several models (either SNcc or SNIa) are available and can be updated or created.

I was born in 1989 in Brussels (Belgium). After high school, I did a bachelor in physics at the Université Libre de Bruxelles, and a master in space sciences at the University of Liège, before starting my PhD in the Netherlands. In my spare time, I play keyboards (self-taught) and sports (swimming, fencing, indoor football). In addition to astronomy (both research and teaching), I have interests in cinema, rock/jazz music, and actuality.
