The dependence of the intracluster light fraction on galaxy cluster properties
Louisa Canepa, Sarah Brough, Mireia Montes +1
We use machine learning to measure the intracluster light (ICL) fractions of 177 galaxy groups and clusters identified from Hyper Suprime-Cam Subaru Strategic Program imaging to ex…

Intra-Cluster Light as a Dynamical Clock for Galaxy Clusters: Insights from the MAGNETICUM, IllustrisTNG, Hydrangea and Horizon-AGN Simulations
Lucas C. Kimmig, Sarah Brough, Klaus Dolag +19
As the most massive nodes of the cosmic web, galaxy clusters represent the best probes of structure formation. Over time, they grow by accreting and disrupting satellite galaxies,…

Measuring the intracluster light fraction with machine learning
Louisa Canepa, Sarah Brough, Francois Lanusse +2
The intracluster light (ICL) is an important tracer of a galaxy cluster's history and past interactions. However, only small samples have been studied to date due to its very low s…
