Yu-Heng Lin

Yu-Heng Lin is a Postdoctoral Scholar Research Associate in Astronomy at the California Institute of Technology, affiliated with the Division of Physics, Mathematics and Astronomy. His research focuses on high-redshift galaxies, reionization processes, and observational cosmology. Lin employs advanced telescopes like the James Webb Space Telescope (JWST) and Hubble to study galaxy evolution, Lyman-alpha emission mechanisms, and the interplay between cosmic structure formation and intergalactic medium properties.

His work emphasizes empirical models of reionization history, mid-infrared abundance studies, and systematic bias corrections in escape fraction measurements. Lin's contributions include analyzing galaxy properties at redshifts exceeding 8, studying Lyα emitters, and investigating the neutral hydrogen fraction at z=10.6 using state-of-the-art observational techniques.

He collaborates with institutions like the Infrared Processing and Analysis Center (IPAC) and participates in large-scale surveys such as CLUTCH and PASSAGE. While no formal awards or students are listed, his research bridges observational data with theoretical frameworks to understand early-universe galaxy formation and cosmic reionization dynamics.
