The intra-cluster light as a tracer of the total matter density distribution: a view from simulations

10 Mar 2020 Asensio Isaac Alonso Vecchia Claudio Dalla Bahé Yannick M. Barnes David J. Kay Scott T.

By using deep observations of clusters of galaxies, it has been recently found that the projected stellar mass density closely follows the projected total (dark and baryonic) mass density within the innermost ~140 kpc. In this work, we aim to test these observations using the Cluster-EAGLE simulations, comparing the projected densities inferred directly from the simulations... (read more)
