- 요약As light travels from the furthest reaches of our universe to our telescopes, it encounters clusters of galaxies, hot gas, and the overarching large-scale structure of our universe. These encounters alter the paths and energy levels of the photons, enabling us to use this light from the Cosmic Microwave Background (CMB) to learn about the earliest stages of our universe and the large-scale structure we observe today. The Atacama Cosmology Telescope (ACT) was a telescope in Chile that observed the CMB from 2008 to 2022. Observations from ACT, combined with observations from complementary surveys, can be used to probe the growth and structure of our universe.This work presents a detailed overview of two major data releases from ACT, along with tools developed to allow the community to use these data products. I also present a cross-correlation analysis of ACT, DES, and BOSS data that uses a combination of the kinematic and thermal Sunyaev-Zel'dovich effects to probe the density, pressure, and temperature profiles of galaxy clusters. I then present work that combines ACT and BOSS data to probe diffuse filaments that make up our cosmic web. To do so, I measure the radial profiles of filaments found using the DisPerSE algorithm and BOSS data in Compton-y and lensing maps produced by the ACT collaboration.Lastly, I present work dedicated to generating maps of CMB observables derived from simulations of large-scale structures. We rely on simulations to deepen our understanding of physical processes, validate our analytical pipelines, forecast our errors, and build up our understanding of our measurements.
