Abstract Details

2016, Doctor of Philosophy, Ohio State University, Physics.
The universe is dominated by unknown elements, dark energy and dark matter. The mysterious nature of the universe is not limited to the dark components. The present day census of ordinary matter (baryons) in the universe is incomplete. This thesis present the work I have done to uncover the nature of dark energy and dark matter as well as understanding the baryon content in the local universe. Chapter 2 presents an analysis of the baryon content in the local universe as traced by X-ray absorption systems. Chapter 3 present the effects of streaming velocities on the baryon acoustic oscillation scale. Chapter 4 is introduces a new galaxy bias model, the environment dependent halo occupation distribution model. Chapter 5 presents a unique algorithm to compute convolution integrals in cosmological perturbation theory. p
