Biography
Cole was born in the city of St. Louis and grew up in a small town of Barnhart just 1 hour South of St. Louis city. In high school he attended Seckman High School in Imperial and graduated in 2018. He immediately began his bachelor's in physics at Missouri S&T that fall. In Spring 2022 he graduated with both a bachelor's in physics and Math and began his PhD. at S&T in the fall. Presently, he works as a graduate teaching instructor teaching Physics 1135 recitation and does research in cosmology under Dr. Shun Saito.

Abstract:
Three-dimensional maps of galaxies probe the large-scale structure of the Universe with which we are supposed to answer fundamental questions such as how the Universe began, or more specifically, what drove cosmic inflation. Nevertheless, we do not have a rigorous understanding of, given a map of galaxies, how much information on the inflationary parameters we can extract and what is the most optimal way to analyze the map. Previous studies have explored this question for single-field analyses, such as galaxy number density. In this work, we extend these approaches to incorporate multiple fields. First, we demonstrate that our framework recovers previous results under specific conditions. Additionally, using a toy model with multiple fields, we achieve a higher signal-to-noise ratio compared to prior methods. Finally, applying our approach to a subset of DESI data, we show further improvements in signal-to-noise ratio over existing analyses.
