Several key, open questions in astrophysics can be tackled by searching for and<br/><br/>mining large datasets for transient phenomena. The evolution of massive stars and<br/><br/>compact objects can be studied over cosmic time by identifying supernovae (SNe) and<br/><br/>gamma-ray bursts (GRBs) in other galaxies and determining their redshifts. Modeling<br/><br/>GRBs and their afterglows to probe the jets of GRBs can shed light on the emission<br/><br/>mechanism, rate, and energetics of these events.<br/><br/>In Chapter 1, I discuss the current state of astronomical transient study, including<br/><br/>sources of interest, instrumentation, and data reduction techniques, with a focus<br/><br/>on work in the infrared. In Chapter 2, I present original work published in the<br/><br/>Proceedings of the Astronomical Society of the Pacific, testing InGaAs infrared<br/><br/>detectors for astronomical use (Strausbaugh, Jackson, and Butler 2018); highlights of<br/><br/>this work include observing the exoplanet transit of HD189773B, and detecting the<br/><br/>nearby supernova SN2016adj with an InGaAs detector mounted on a small telescope<br/><br/>at ASU. In Chapter 3, I discuss my work on GRB jets published in the Astrophysical<br/><br/>Journal Letters, highlighting the interesting case of GRB 160625B (Strausbaugh et al.<br/><br/>2019), where I interpret a late-time bump in the GRB afterglow lightcurve as evidence<br/><br/>for a bright-edged jet. In Chapter 4, I present a look back at previous years of<br/><br/>RATIR (Re-ionization And Transient Infra-Red Camera) data, with an emphasis on<br/><br/>the efficiency of following up GRBs detected by the Fermi Space Telescope, before<br/><br/>some final remarks and brief discussion of future work in Chapter 5.
