2026

Atthaporn Pramoun is a physics student in the Faculty of Science at Mahidol University, Bangkok. His senior research project, advised by Asst. Prof. Suraphong Yuma (Mahidol University) and Krittapas Chanchaiworawit (NARIT), builds a unified catalog of protocluster candidates at z = 1.5–3.0 from the JWST PASSAGE and SAPPHIRES pure-parallel surveys — from source extraction and photometric redshifts to overdensity and friends-of-friends identification — and then characterizes the candidates' ages, gas fractions, and quenched fractions with SED fitting.
