My name is Jérémy Fensch. I am a Research Fellow at ESO in Garching.
My research focuses on galaxy collisions and induced formation of stars, star clusters and tidal dwarf galaxies. I am also interested in the evolution of globular clusters and the evolution of galactic structures with redshift.
Globular cluster systems around massive galaxies show a bimodal color distribution, composed of blue and red clusters. However, the more massive blue clusters are, the redder they look. An explanation for this trend might reside in the retention of supernovae ejecta by the star cluster during its youth.
