A faint glow to trace the dark matter
November 27th, 2018
The faint glow produced by the stripped stars of the galaxies within clusters is shown to follow the dark matter distribution with extreme accuracy. In this contribution, we will show how the Intra-Cluster light can be used to trace the dark matter distribution of galaxy clusters just using deep imaging. This finding opens up the possibility of exploring the distribution of dark matter in hundreds of galaxy clusters and test the current LCDM paradigm.
