Active Galactic Nuclei (AGN) are galaxies that host accreting supermassive black holes. These powerful sources inject enormous amounts of energy into their surroundings, influencing how galaxies evolve through AGN feedback.
Radio astronomy provides a unique window into AGN feedback revealing both aged emission from past AGN activity and recently accelerated particles associated with jets. Together, these observations allow astronomers to understand the impact AGN have on host galaxies.
I will introduce AGN feedback and discuss both evidence for its role in galaxy evolution. I will highlight the crucial role of radio astronomy in revealing the influence of AGN on their host galaxies, and present cutting-edge research being undertaken with the latest generation of radio facilities.

About Emmy Escott

Dr Emmy Escott is a fellow of low-frequency radio astronomy at CSIRO in Perth, Australia. She previously completed her PhD at Durham University where she created the first sub-arcsecond resolution image of the Boötes Deep Field at 144 MHz. Her science interest includes linking powerful outflows from galaxies which host an active supermassive black hole (AGN) to their high-resolution morphologies at low-frequencies. She is currently working on commissioning a new telescope with stations soon to be spread across Australia and parts of Asia.
