Xin Wang 王鑫
Postdoctoral Research Associate at Caltech/IPAC


Xin Wang (王鑫) is currently a postdoctoral research associate at Caltech/IPAC. Before Caltech, Xin earned his Ph.D. in Astronomy & Astrophysics from UCLA in 2019. Before coming to California, Xin obtained both M.Sc. and B.Sc. in Astrophysics from Nanjing University in China. Since 2020, Xin has been leading the MAMMOTH-Grism HST Cycle-28 Medium Program, obtaining 45 orbits of deep slitless spectroscopy in the density peaks of three most massive galaxy protoclusters at z~2-3. Xin is selected by NASA as one of the participants in the inaugural JWST master class, and has hosted several JWST proposal planning workshops for the community.

Xin has great expertise in the reduction and analysis of wide-field slitless spectroscopic data acquired by HST near-infrared grisms, and is capable of performing realistic grism simulations for future space missions, e.g., JWST. Xin developed a novel method of spatially resolved analysis of high-redshift galaxies via slitless spectroscopy, to study the effects of gas flows, star formation and galactic feedback on the baryon cycle and galaxy chemo-structural evolution. Xin is the co-I of three approved JWST Cycle-1 programs, including the 591-hour pure-parallel PASSAGE program and the GLASS ERS program. Xin is also a core member of the UVCANDELS program.
