CAREER: Near- and Far-Infrared Background Light and the Astrophysical and Cosmological ImplicationsAbstractAST-0645427PI: Asantha CoorayDr. Cooray will carry out a comprehensive research program to characterize the underlying astrophysical and cosmological information contained in the infrared background (IRB) spatial anisotropies at near- and far-IR wavelengths. In the near-IR regime, signatures of primordial galaxies in the background spatial fluctuations will be studied. At far-IR wavelengths, clustering information of dusty, star-forming galaxies will be measured. The main goal of this research program is to expand the science case for anisotropy measurements of IRB and to provide a strong theoretical background to interpret these measurements just as the case has been with respect to CMB anisotropy experiments. As a part of this research project, Dr. Cooray plans to provide training and research experiences for students, with an emphasis on creating opportunities for undergraduate students. This includes direct involvement in international collaborations such as Akari, based in Japan, and Herschel SPIRE, based mostly in the UK. Students will attend collaboration meetings in these countries and will be trained to work with and learn from foreign partners. The PI plans to integrate elements of this research program and other topics in cosmology into a Computational Physics course Dr. Cooray teaches at UC Irvine where the students are recruited for the research program. Over the next three years, Dr. Cooray will also develop a completely new course on how to do "Order of Magnitude Physics" targeting juniors and will also make available the course material publicly from a website. Dr. Cooray will also update an existing Voyager-era "Space Science" course, in the introductory astronomy sequence targeting non-science majors, to a course on "Space Astronomy" as a way to bring new astronomical missions and their results to the classroom.This award is funded by the NSF Division of Astronomical Sciences

研究方向：近、远红外背景光及其天体物理学和宇宙学意义[j]。Cooray将开展一项综合研究计划，以表征红外背景（IRB）在近红外和远红外波长的空间各向异性中包含的潜在天体物理和宇宙学信息。在近红外波段，原始星系在背景空间波动中的特征将被研究。在远红外波段，将测量尘埃、恒星形成星系的群集信息。本研究计划的主要目标是扩展IRB各向异性测量的科学案例，并提供一个强大的理论背景来解释这些测量，就像对CMB各向异性实验的情况一样。作为该研究项目的一部分，Cooray博士计划为学生提供培训和研究经验，重点是为本科生创造机会。这包括直接参与国际合作，如总部设在日本的Akari和总部设在英国的Herschel SPIRE。学生将参加这些国家的合作会议，并接受培训，与外国伙伴合作并向其学习。PI计划将这个研究项目的元素和宇宙学的其他主题整合到Cooray博士在加州大学欧文分校教授的计算物理课程中，那里的学生被招募参加这个研究项目。在接下来的三年里，库雷博士还将针对大三学生开发一门全新的课程，内容是如何做“数量级物理”，并将课程材料从网站上公开。库雷博士还将把现有的“旅行者”时代的“空间科学”课程（针对非科学专业学生的入门天文学课程）更新为“空间天文学”课程，以便将新的天文任务及其结果带入课堂。该奖项由美国国家科学基金会天文科学部资助
