Quasars, Blazars, and Radio Galaxies are the most violent activities seen in the universe since the Big Bang itself. All these objects are aspects of active galactic nuclei, powered by supermassive black holes. The physics of these objects is not yet fully understood, though various aspects have become clearer since they were first discovered in the middle of the 20th century. High-resolution radio astronomy has been especially key to the development of our understanding. Energy is transported from the nucleus by oppositely directed jets that can be many millions of light-years long. This kind of violent activity was much more common early in the history of our universe. At this live-streamed talk, Galen Gisler will discuss the observed characteristics of these objects and our understanding of how they work.
