The goal of this project is to investigate the ejection of matter from the nuclei of galaxies via quasar winds, the link to accretion of matter into the nuclei, and the feedback between these processes that affects the formation and evolution of typical massive galaxies and larger-scale structures. The PIs and their students will use data on 150,000 quasars from the Baryon Oscillation Spectroscopic Survey (BOSS) of the Sloan Digital Sky Survey-III (SDSS-III). They will study variability in the broad absorption line troughs that characterize quasar winds. Broader impacts of the work include training of undergraduate and graduate students, and postdocs. Catalogs and data products produced by the research will be publicly released, and the PIs and their students will conduct summer workshops for high-school and middle-school teachers.

该项目的目标是研究通过类星体风从星系核喷射物质，物质吸积到核中的联系，以及这些过程之间的反馈，这些过程影响典型的大质量星系和大尺度结构的形成和演化。 PI和他们的学生将使用来自斯隆数字巡天III（SDSS-III）的重子振荡光谱巡天（BOSS）的15万个类星体的数据。 他们将研究表征类星体风的宽吸收线槽的变化。 这项工作的更广泛影响包括对本科生、研究生和博士后的培训。 研究产生的目录和数据产品将公开发布，PI及其学生将为高中和中学教师举办夏季研讨会。
