Measurements Of The Sunyaev- Zel'dovich Effect In A Herschel- Spire Survey Of Galaxy Clusters, Ryan Wills

As the largest gravitationally bound objects in the modern universe, galaxy clusters are excellent environments for studying the large-scale structure and evolution of matter in the cosmos. The environments of galaxy clusters change significantly over time from sites of intense star formation at z ~ 2-4 to mostly quenched objects with very little star formation in the current epoch. During this evolution, galaxy clusters also establish an intra-cluster medium (ICM) of hot plasma, which is typically firmly in place by a redshift of z ~ 1. The properties of the ICM are intimately tied to the formation history of the …

Commissioning The Tomographic Ionized-Carbon Mapping Experiment, Benjamin James Vaughan
Theses
Line intensity mapping is a novel technique that traces the evolution of cosmological structure sourcing a particular emission line through measurements of the aggregate emission of all galaxies along a line of sight. The Tomographic Ionized-carbon Mapping Experiment (TIME) is a far infrared waveguide imaging spectrometer that operates from 183-323 GHz, allowing it to trace the emission of the singly ionized carbon fine structure line ([CII], 157.7 µm) from redshift 5 to 9 to probe the infrared emission from star formation during the Epoch of Reionization. Further, TIME will also perform line intensity mapping observations of several carbon monoxide rotational …

A Study Of Large-Scale Structure Evolution Through Sunyaev-Zel’Dovich Corrections In Massive Clusters, Victoria Butler
Theses
The evolution of large-scale structure is traced by galaxy clusters, which are groups of galaxies gravitationally bound by a shared envelope of dark matter on scales of 1-10 Mpc. They are filled with an intra-cluster medium (ICM) consisting of a diffuse hot plasma with characteristic temperature $10^7K. While ICM models match reasonably well with observations, smaller-scale astrophysical processes in clusters can complicate interpretations of derived thermodynamic properties. These can include cluster-cluster mergers, feedback from active black holes, and accretion, among several others. The complex relationship between these processes and the properties of the ICM must be understood to use clusters …
