CAREER: dark matter and black holes over cosmic timeAbstractAST-0642621PI: Tommaso TreuDr. Treu will use innovative observational strategies and analysis techniques to map the evolution of the internal structure of spheroids (i.e. elliptical and lenticular galaxies, and bulges of spiral galaxies) over cosmic time, with a focus on the redshift interval z = 0-1, an era when spheroids undergo substantial evolution. This research places its emphasis on dark matter and black holes. Whereas recent studies have made progress on the evolution of their stellar populations, empirical data on the co-evolution of stars, dark halos, and black holes are needed to understand the formation of spheroids in a cosmological context. The new observations made under this award will provide an empirical benchmark for the next generation of theoretical models of galaxy formation. Dr. Treu will also work on several educational/public outreach componentsas a part of this award. The general public and K-12 student efforts, based on a collaboration with the Santa Barbara Museum of Natural history (SBMNH) and the Las Cumbres Observatory (LCOGT), will consist of a series of public lectures in the Museum auditorium. In addition, the LCOGT is donating a 32" telescope to the UC-operated Sedgwick Natural Reserve. Dr. Treu will work with K-12 teachers and the SBMNH to establish an astronomy curriculum at Sedgwick. At the undergraduate non-science major level, Dr. Treu is developing, in collaboration with the UCSB Religious Studies (RS) and History (H) departments, a course entitled "Origins", which will be organized around questions such as "What's the Universe made of?". For each question, students will be exposed to the distinct methodologies employed by scientists, philosophers, theologians, so as to appreciate the essence and the importance of the scientific method. This award is funded by the NSF Division of Astronomical Sciences

职业生涯：宇宙中的暗物质和黑洞摘要AST-0642621PI：托马索·特鲁博士。TREU将使用创新的观测策略和分析技术绘制球体内部结构随宇宙时间的演化图(即椭圆和透镜星系，以及螺旋星系的凸起)，重点放在红移间隔z=0-1，这是一个球体经历实质性演化的时代。这项研究的重点是暗物质和黑洞。虽然最近的研究已经在恒星群的演化方面取得了进展，但需要关于恒星、暗晕和黑洞共同演化的经验数据，才能在宇宙学背景下理解球体的形成。根据这一奖项进行的新观测将为下一代星系形成的理论模型提供一个经验基准。作为该奖项的一部分，特鲁博士还将在几个教育/公共宣传部分开展工作。在与圣巴巴拉自然历史博物馆(SBMNH)和拉斯坎布雷天文台(LCOGT)合作的基础上，普通公众和K-12学生的努力将包括在博物馆礼堂的一系列公开讲座。此外，LCOGT还向加州大学运营的塞奇威克自然保护区捐赠了一台32英寸的望远镜。特鲁博士将与K-12教师和SBMNH合作，在塞奇威克开设天文学课程。在本科非理科专业，特鲁博士正在与UCSB宗教研究(RS)和历史(H)系合作开发一门名为“起源”的课程，该课程将围绕诸如“宇宙是由什么组成的？”等问题来组织。对于每一个问题，学生将接触到科学家、哲学家、神学家所采用的不同方法，从而领会科学方法的本质和重要性。该奖项由美国国家科学基金会天文科学部资助。
