Intracluster Light as a Probe for Dark Matter: Exploring SIDM and CDM with C-EAGLE Sims

Jaewon Yoo, Ellen L. Sirks, Cristiano G. Sabiu +5

We assess whether intracluster light (ICL) can serve as an observational discriminator of dark matter physics. The self-interacting dark matter (SIDM) model has gained increasing a…
