Title: The extremes of galaxy and black hole formation

We have recently seen a remarkable convergence in our overall understanding of how galaxies in the Universe form, through the collapse of gas in dark matter halos, and growth through star formation and merging over cosmic time. However, many of the key physical processes, such as gas dynamics, feedback, and the growth and impact of supermassive black holes, are complex and challenging to understand in detail. One observational technique is to study the extremes of galaxy and black hole formation where these effects are most pronounced. I will present observational studies of a few of these extreme cases, including compact starbursts driving powerful winds, rapidly growing supermassive black holes that are heavily obscured by gas and dust, and supermassive black holes in low-mass dwarf galaxies, Finally, l will point toward some exciting possibilities with new observing facilities. This work has been generously supported by NASA and the National Science Foundation.
