Abstract
The Universe is full of a zoo of galaxies that serve as beacons tracing the underlying structure of dark matter in the Universe. Galaxies exhibit a diverse array of structural properties and observed brightnesses, all of which provide clues to their evolution and the underlying structure of space. The galaxy in which we reside, the Milky Way, provides an exclusive opportunity for testing models of galaxy formation and cosmology courtesy of our proximity to the stars and dust that shape the Galaxy. Data-model comparisons of Milky Way observations to simulations, and observations of Milky Way-like galaxies are a compelling way to improve our understanding of galaxy formation and evolution.
However, we still currently lack insight into how the Milky Way fits in with the general galaxy population, an issue stemming from our location within the disk of the Milky Way. Dust blocks a large portion of our view of the Milky Way and we are unable to capture bulk integrated properties like we can for other galaxies. The focus of this thesis is on utilizing state-of-the-art statistical techniques and models to surpass these issue, addressing discrepancies in both simulations and observations, to improve our understanding of the Milky Way and how it connects to other galaxies as a means for answering questions on galaxy evolution.
