[ASA] REMINDER: The History and Mystery Series - N. Seymour

[GIULIA GOLINI]

Dear ASA Community,


Thank you to everyone who has already registered for the next History & Mystery session this Thursday:


Professor Nick Seymour (CIRA)


What Powers Active Galactic Nuclei (Wrong Answers Only)?


Abstract: Over the decades active galactic nuclei (AGN) have moved from being esoteric objects to being a fundamental part of galaxy evolution via feedback processes. There is now (almost) universal consensus that AGN are powered by accretion onto supermassive black holes. However, this was not the first explanation and even after it was first proposed in the mid-1960's, the idea took decades to become firmly accepted. In this talk I will review some of the early ideas put forth to explain the origin of the power produced by quasi-stellar objects. These include exotic supernovae, stellar collisions, massive super-stars as well as stranger ideas. I will then look to see if we can learn anything from these ideas.
