<span style="font-size: 14px;"><b>Abstract: </b></span><span style="font-size: 14px;">The brightest cluster galaxy (BCG) and the surrounding intracluster light (ICL) together dominate the stellar content at the centres of galaxy clusters, but their physical
distinction remains blurred. Using hydrodynamical simulations, we investigate the formation of the BCG and ICL components across a sample of massive clusters. First we achieve this via hindcasting, tracking the components we see at z=0 back through cosmic
time. We then take what we learned from this process to implement forecasting, allowing us to dynamically split the BCG and ICL components at the current time. Our results provide motivation for both observational and theoretical attempts to split the BCG
from the ICL.</span></div>
