Featured Presentation – Extragalactic Astronomy in a Nutshell
The majority of deep sky objects are classified as galaxies. Indeed, galaxies constitute a third of the Messier Catalogue, and more than three quarters of the New General Catalogue. Consequently the majority of amateur astronomers, and, as result of popular science fiction, the public at large, are familiar with the concept of a galaxy. However, it is only in the last century that science has come to understand these faint fuzzies in the eyepiece to be distinct physical objects separate from our own Milky Way. In this talk I will review the milestone achievements of this renaissance in astrophysics before discussing the modern approach to extragalactic astronomy. In doing so, we will examine not only the different types of galaxy we can observe, but how these observations help clarify our understanding of the universe we inhabit.
About the Speaker
Yjan Gordon is a British observational astrophysicist specialising in the field of galaxy evolution, and currently working at the University of Manitoba. His research is primarily aimed toward understanding how the growth of the supermassive black hole at the core of a galaxy (the quasar phenomenon) can be influenced by the interaction of that galaxy with its larger environment.
