报告题目：Mapping the Dust Obscured Cosmic Star Formation
报告人：王为豪 副研究员 (中国台湾“中央研究院”)
Abstract：Through the observations of the extragalactic background radiation, it is known that at least half of the radiation produced by galaxies in the cosmic history is absorbed by dust and reradiated in the far-IR. Therefore, a complete understanding of the formation and evolution of galaxies requires fully mapping the sources that produce the far-IR background. However, only until recently can we study the L* members in the far-IR galaxy population, thanks to new wide-field cameras and sensitive interferometers for the submillimeter. In this talk, I will present our recent deep multiwavelength surveys for the studies high-redshift star-forming galaxies. Most of these surveys are targeted on the dust obscured galaxies using various submillimeter facilities, including the SMA, JCMT, and ALMA. On the other hand, I am also conducting CFHT and Subaru imaging surveys to enhance our understanding of the UV-selected star-forming population, which is less obscured. With these new-generation UV and far-IR observations, we can better constrain the cosmic star-formation history and to even connect the star-forming galaxies with the underlying dark matter halos.
