Advisor: Prof. Alexander Heger. 1 computer file (PDF); xiv, 196 pages, appendices A.One of the frontiers in modern cosmology is understanding the end of the cosmic dark age, when the first luminous objects (e.g., stars, supernovae (SNe), and galaxies) re-shaped the primordial Universe into the present one of much complexity. In this dissertation, I use numerical simulations to study the evolution of the first supernovae and their cosmological consequences. To push the model frontiers of the first SNe, I apply new numerical approaches to advance models of the first SNe. The goal of my dissertation is to provide a better understanding of the first SNe that may be observed by the large telescopes of the future.en-USComputational astrophysicsCosmologySupernovaeThe first galaxiesThe first starsThesis or Dissertation
