- 요약One hundred years after Albert Einstein predicted their existence, the Laser Interferometer Gravitational-Wave Observatory (LIGO) detected distortions in the fabric of spacetime known as gravitational waves. This discovery provided for the first time direct evidence of one of the most energetic events in the universe: the merger of two black holes once in an orbit around each other. My research addresses a key unresolved question: How do these gravitational wave sources form in nature? For more than two decades, rapid binary population synthesis codes have been used to address this question. Although these codes have been instrumental in our general understanding of merging compact objects, most rely on analytical fits of single-star evolutionary tracks and parameterized models for interactive phases of binary evolution. This has led to large prediction uncertainties and an inability to explain current observations. Simultaneously, we are experiencing a rise in the number of merger detections and with the advent of next-generation instruments this number will increase 1000-fold, revealing a larger, more diverse population. In my dissertation I focus on improving our understanding of the formation of gravitational wave sources through a comprehensive and physics-focused approach to the details of binary evolution. In this dissertation, I will 1) show how my study of merging binary black holes with the state-of-the-art stellar evolution code MESA challenges common wisdom regarding their formation, 2) describe how incorporating key electromagnetically-observed binary systems enables a more comprehensive study of the formation of gravitational wave sources, and 3) provide an example illustrating the necessity for collaborative research in developing improved, physically-motivated models for binary evolution.
