Abstract Details

2023, Doctor of Philosophy, Case Western Reserve University, Physics.
SPT-3G is a new camera on the South Pole Telescope, currently being used to observe the sky in the millimeter-wavelength and make maps of the Cosmic Microwave Background (CMB). The CMB can be used to probe the origins of the universe and understand its subsequent evolution and the growth of structure. Clusters of galaxies, the largest gravitationally bound objects in the universe, trace out the distribution of matter across the universe. Observations of the CMB can be used to detect and characterize galaxy clusters via the Sunyaev Zel’dovich effect, wherein CMB photons are inverse Compton scattered off of hot gas within galaxy clusters. This effect can be used to measure the temperature evolution of the CMB as the universe expanded. In this thesis I give background on cosmology, describe the SPT-3G instrument and my role in its development, describe the software pipeline I wrote to detect galaxy clusters using SPT-3G, and give the new constraint on CMB temperature evolution that we have made using the 2019 and 2020 SPT-3G observations.
