Travis Fischer, Space Telescope Science Institute

Active galaxies are some of the most fascinating objects in the universe. They emit copious amounts of energy, often far exceeding the energy output of an entire galaxy of stars. But what makes them so active? Dr. Fischer will explore the nature of active galaxies, including their energetic processes and the role they play in shaping the universe we see today. Hear about some of the latest research in the field, including the use of telescopes and other observational tools to study these enigmatic objects. Join us on this journey to the heart of the most powerful objects in the cosmos.
