A bla ck hole is a massive body whose surface gravity is so great that light cannot escape its gravitational pull. A growing understanding of the connection between galaxies and their central black holes has emerged that relates some of the properties of the black hole\, whose gravity influences only the central 1/10\,000 of the galaxy\, to the global p roperties of the entire galaxy. Furthermore the latest galaxy formati on and evolution theories require the input of energy from the black h ole into the galaxy to achieve the size\, shape and number density of the galaxies we observe today. These facts suggest that the growth mec hanisms of the black hole and galaxy must be connected. However\, deta ils of the physical processes behind this connection are not yet under stood. I will present an overview of the status of the field and then discuss my research to understand the nature of some of the most massi ve of these objects that are in the process of consuming massive amoun ts of matter from their host galaxies. These objects are Quasi-Stellar Objects or QSO's\, which shine brightly in the sky due to the excess gas that escapes their feeding process.
