Research summary
AI-generated

This researcher's publication record centers on active galactic nuclei (AGN) and quasars, particularly using a technique called reverberation mapping, which tracks time delays between light variations in different wavelengths to probe the structure of accretion disks around black holes. The work includes studies of intermediate-mass black holes, X-ray and infrared variability, and using quasars as tools to measure cosmological distances. Note that a few unrelated titles (on BIM engineering software and animal science) also appear in the record, which may reflect shared author names rather than a single individual's work.
