About
Cheongho Han is a leading figure in gravitational microlensing, a powerful technique for detecting exoplanets and faint stellar objects. His research centers on the development of real-time detection systems and the analysis of complex microlensing events, particularly those involving binary systems and low-mass objects. Han’s major contributions include pioneering the first automated real-time detection of a weak microlensing anomaly with the ARTEMiS system, leading to the discovery of a brown dwarf or stellar binary in the event OGLE-2008-BLG-510 (25 citations). He also played a key role in the Angstrom Project, creating the Angstrom Project Alert System (APAS) to identify extragalactic microlensing events in real time across the Andromeda Galaxy (17 citations). These innovations have significantly advanced the field, enabling faster and more efficient detection of rare astrophysical phenomena. Han’s work has been instrumental in pushing the boundaries of microlensing surveys, with his most-cited papers demonstrating his impact in both Galactic and extragalactic contexts. His achievements highlight a career dedicated to refining observational strategies and unlocking the secrets of dark, distant worlds.
