Physics Astrophysics physics high energy cosmic rays experiment detector microwave neutrinos astrophysics The study of ultra-high energy (UHE) cosmic particles is frequently characterized by its low statistics, and a central problem of the field is to find novel ways to navigate this challenge. The research presented in this dissertation attempts to address this problem in two ways: first, by investigating microwave radiation as a new method of UHE cosmic ray detection, and second, by using a multi-messenger (proton and neutrino) analysis to determine what current and next generation UHE neutrino detectors may be able to reveal about UHE astrophysical sources. The cosmic ray detector (called AMBER) is primarily a joint collaboration between Ohio State and the University of Hawaii. In May/June 2011 the AMBER experiment was installed at the Pierre Auger Observatory in Malargue, Argentina, and began taking data in coincidence with the observatory’s surface detector array. This work presents a description of the experiment, a calibration based on an astrophysical radio source (the Milky Way galaxy), and an analysis of data. The second half of this document describes a multi-messenger analysis performed with co-authors Amy Connolly and Shunsaku Horiuchi on a publication in preparation. Fits to Pierre Auger 2013 data are used in conjunction with a spectral model and simulations of UHE neutrino detectors to explore the UHE source parameters of cosmic evolution and source spectrum cutoff. Constraints provided using the effective areas of the ANITA 3, ARA, and EVA detectors are considered. 2015-05-28 English text The Ohio State University / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=osu1429799044 http://rave.ohiolink.edu/etdc/view?acc_num=osu1429799044 unrestricted This thesis or dissertation is protected by copyright: some rights reserved.
