Euclid Quick Data Release (Q1). A systematic study of the intracluster light fraction at 0.2
We present a homogeneous analysis of the intracluster light (ICL) in approximately 300 galaxy clusters spanning $0.2<z<1.5$, combining Sunyaev-Zeldovich-selected clusters from the South Pole Telescope and optically selected clusters from Euclid, and comparing results with Hydrangea simulations. We measured the brightes...
