Starbursts and active galactic nuclei (AGN) are predominantly driven by galaxy mergers, i.e., the collision of two galaxies, but isolated galaxies, e.g., our Milky Way, can also be subject to these phenomena. Therefore this thesis is divided into two parts: in partwe investigate starbursts and AGN due to galaxy mergers and in part II we examine the Galactic Center (GC), i.e., the center of our Milky Way. In part I we will focus in particular on the timing of starbursts and AGN activity during a merger event. Recent observations indicate a time lag between these two phenomena in the sense that first the merger produces a starburst, followed by, after a time span of 200-300 million years, an episode of AGN activity. To explain this time lag ...
