Rate My Professor Hang Yu

Yu's research specializations encompass gravitational-wave astrophysics, compact objects, tidal interactions, and LIGO instrumentation and data analysis. Theoretically, he explores dynamical tides in binary systems, the high-eccentricity migration and evolution of proto-hot Jupiters and coalescing binaries of compact objects, as well as Newtonian and post-Newtonian effects in hierarchical triple systems. Experimentally, he contributes to improving the sensitivity of the Laser Interferometer Gravitational-Wave Observatory (LIGO) and employs machine learning on LIGO data to identify additional binary black hole mergers. He has received NASA funding for his project on dynamical tides in the high-eccentricity migration of close-in exoplanetary systems. Yu has authored or co-authored 269 research works, including key publications such as "Gravitational radiation-driven chaotic tide in a white dwarf-massive black hole binary" (2025), "Effective-one-body model for coalescing binary neutron stars" (2025), "Are WASP-107-like Systems Consistent with High-eccentricity Tidal Migration?" (2024), "Relativistic and Dynamical Love Numbers" (2025), and major contributions to LIGO Scientific Collaboration papers like "Prospects for observing and localizing gravitational-wave counterparts" (2020). His scholarship has amassed over 51,000 citations on Google Scholar, underscoring his significant influence in theoretical astrophysics and gravitational-wave science. Yu advises doctoral students, including Ethan McKeever, recipient of a 2025 NASA FINESST grant for gravitational-wave research.
