This lecture covers the components of galaxy clusters, including baryonic mass, hot gas, dark matter, and magnetic fields. It also delves into the historical perspective of cluster discovery, such as Messier and Herschel's contributions. The instructor discusses the Coma Cluster, the Bullet Cluster, and the gravitational lensing effect in clusters. Furthermore, the lecture explores the role of X-ray and radio emissions in studying galaxy clusters, highlighting phenomena like the Intra Cluster Medium and magnetic field pressure. The presentation concludes with insights into gravitational lensing, showcasing how it distorts space-time and produces multiple images. Various examples, such as the Bullet Cluster and the Coma Cluster, are used to illustrate key concepts.
