Description
Although there is a developing understanding of the mechanisms by which the diffuse stellar component of galaxy clusters termed the intracluster light (ICL) is formed, no strong consensus has yet been reached on which objects the stars of the ICL are primarily sourced from. We have investigated ICL assembly in the Horizon-AGN simulation (a cosmological hydrodynamical simulation), and in this talk I will relay our findings for the bulk ICL contribution from galaxies with differing stellar masses preceding cluster infall, what range of galaxy masses are responsible for the vast majority of the ICL contributed by galaxies, and what objects are the most significant contributors of ICL stars in a typical cluster - all of which provides insightful context for utilising ICL to discern the dynamics and assembly history of a galaxy cluster.
