Presidential Young Investigator (PYI) Award: QSO Absorption Lines

这项总统青年研究员奖将支持 开发新的仪器和观测， 研究类星体的内在性质， 物质分布沿着视线到这些极端 遥远的物体 吸收线的莱曼-α“森林” 在高红移类星体的光谱中， 归因于前银河系或原银河系物质的介入 与来自大规模的新材料的元素组成 砰 通过开发新的，更强大和敏感的 光谱仪，并使用它们来研究这种材料， 这位杰出的年轻科学家将探索 宇宙早期的物理过程

This Presidential Young Investigator award will support the development of new instrumentation and observations dedicated to the study of the intrinsic properties of quasars and the distribution of matter along the line of sight to these extremely distant objects. The Lyman-alpha "forest" of absorption lines seen in the spectra of high redshift quasars is generally ascribed to intervening pre-galactic or proto-galactic material with the elemental composition of material fresh from the big bang. By developing new, more powerful and sensitive spectrometers and using them to study this material and the quasars beyond them, this outstanding young scientist will probe the physical processes occurring in the very early universe.
