中国科大寰宇开物天文讲坛 Probing Cosmic Reionization with JWST/NIRSpec Lyα observations 2024年7月1日 16:00 蔻享学术 扫码查看精彩直播 // 嘉宾简介 陈祖诒 Zuyi Chen (陈祖诒) is a PhD candidate in Steward Observatory, the University of Arizona, working with Prof. Dan Stark. He uses a combination of JWST NIRCam imaging and NIRSpec spectroscopy to study galaxies in the first billion years after the Big Bang, with a particular focus on their stellar populations, assemble history, and ionizing spectra. He uses these observations as a probe of the timeline of cosmic reionization as well as the growth of ionized bubbles in the early universe. In addition, he is also interested in searching and characterizing extremely metal-poor dwarf galaxies in the local universe, using them as unique laboratories to understand star formation activities at metallicities similar to those in early galaxies. Before coming to Steward, he obtained his B.S. from University of Sc ………………………………
