The Mysteries of Galaxy Evolution - Professor Sarah Brough

In this episode of Astrophysics for All, I'm joined by Professor Sarah Brough, Head of the School of Physics at University of New South Wales and an observational astronomer studying how galaxies grow and evolve over billions of years.Professor Brough explores some of the faintest and most elusive structures in the Universe: tidal features and intracluster light. She explains how these delicate traces reveal galaxies’ hidden histories of mergers, disruption, and transformation. Professor Sarah Brough discusses her research on galaxy evolution, focusing on tidal features and intracluster light. She explains the challenges of detecting these faint cosmic phenomena and the technological advancements that have made such studies possible.
