Adam Gonzalez (Saint Mary's University) - High-velocity outflows in active galactic nuclei 
Every massive galaxy hosts a supermassive black hole at its centre that is a million to a billion times more massive than our Sun. When these black holes actively accrete material from their surroundings they become the most luminous continuous sources of emission in the Universe, so-called active galactic nuclei. The extreme physical conditions manifested nearest the black hole are capable of driving matter out of the central region at velocities nearly the speed of light. This material may form a large-scale tightly collimated outflow (i.e. a jet) or a small-scale diffuse outflow (i.e. a wind). I will present an overview of how these outflows of material are produced, how we study them, and their implications on the formation of the Universe as we know it.
