The intracluster light (ICL) permeating galaxy clusters is a tracer of the cluster assembly history and potentially a tracer of their dark matter structure. In this work, we explore the capability of the Euclid Wide Survey to detect ICL using HE-band... Read More about Euclid preparation. LXX.

Monthly Notices of the Royal Astronomical Society, 539(4), 3058-3076. https://doi.org/10.1093/mnras/staf635

Understanding the processes that transform star-forming galaxies into quiescent ones is key to unravelling the role of environment in galaxy evolution. We present measurements of the luminosity functions (LFs) and stellar mass functions (SMFs) of pas...

Intracluster light is a biased tracer of the dark matter distribution in clusters (2025)
Journal Article

The diffuse stellar component of galaxy clusters known as intracluster light (ICL) has been proposed as an observable tracer of the cluster’s dark matter (DM) halo. Assessing its reliability as a DM tracer requires understanding how the intracluster... Read More about Intracluster light is a biased tracer of the dark matter distribution in clusters.
