Abstract Details

2018, Doctor of Philosophy, Ohio State University, Physics.
The modern study of cosmology is centered around the mysteries of Dark Matter and Dark Energy. The observable Universe, although highly non-linear on small scales, can be described statistically on large scales. Careful study of the large-scale structure of the Universe can provide powerful insights into the structure and evolution of matter, allowing constraints to be placed on the nature of Dark Energy and Dark Matter. This thesis contains the work that I have done to contribute to the understanding of these mysteries, in several specific situations. In Chapter 2, I discuss the effect of NII and Hα line blending on measured redshift-space distortion and baryon acoustic oscillation parameters for the upcoming WFIRST telescope, which will help to measure the evolution of Dark Energy. Chapter 3 presents a radial measurement of the tidal alignment magnitude, providing a complementary method to gauge how strongly galaxies couple with the local gravitational field during formation. Finally, in Chapter 4 I lay the framework for a fully general calculation of the effects of resonant line scattering on the polarization anisotropies of the Cosmic Microwave Background.
