| Description: | Clusters of galaxies provide us the opportunity to study an “ecosystem ” — a volume that is a high-density microcosm of the rest of the Universe. Clusters are signposts for early structure formation, and are moderately isolated, growing on the Hubble timescale from the Cosmic Web. Clusters are excellent laboratories for studying plasma physical processes as well as for studying how super-massive black holes interact with the ambient cluster plasma. The next generation of cluster surveys is well suited to address fundamental problems in physics and cosmology (e.g. [1]), such as further constraining the Dark Energy equation of state [2] or to test whether our understanding of gravity is complete. Time is ripe to tackle the following important questions with clusters on an individual basis or as an entire population using multi-wavelength observational campaigns: • How do clusters form and grow? How does feedback from star, galaxy, and black hole formation impact cluster structure and evolution? What detailed physical processes govern the heating and cooling of cluster cores? Are clusters pre-heated before they are assembled? What are the robust mass observables and scaling relations that can be used for cosmology? |
