The 2019 John Porter Memorial Lecture given by Prof Chris Collins
Understanding the evolution of mass at the centres of clusters of galaxies is essential if we are to be confident that we can explain structure in the wider universe. However, current telescopes and surveys find it difficult to measure the faint light between the galaxies - the Intra-Cluster Light or ICL - even though in total this can be more significant than the more concentrated light of the central galaxy. This talk will look at current challenges in studying the ICL and how they are being overcome, and also look to the near future when new facilities like the Large Synoptic Survey Telescope (LSST) will give an unprecedented view of this elusive but vital part of the cosmos.
The lecture is free, open to, and suitable for all. No booking required.
The John Porter Memorial lecture is an annual lecture organised jointly by the Astrophysics Research Institute and the Institute of Physics.
