AST-9983830EIKENBERRYMultiwavelength studies of the Galactic relativistic jet sources -- the "microquasars" will be carried out. The overall goal of the research is to understand the origin, formation, and evolution of relativistic jets in black hole X-ray binaries. The knowledge gained by these studies will be used to understand black-hole/relativistic-jet systems in our Galaxy and their larger analogs in active galactic nuclei. This research builds on previous work on X-ray and infrared (IR,) studies of the microquasar GRS +105 and other microquasar candidates. Highlights of the scientific work to be carried out include:Coordinated X-ray, IR, and radio observations of relativistic jet formation in the microquasar GRS 1915-105: The previous coordinated X-ray/IR/radio observations of this object provided the first direct, tine-resolved observations of relativistic jet formation in any system. These and other observations have also shown that GRS 1915+105 exhibits many different states of jet-producing and non-jet-producing behaviors. The observational campaigns will help to classify these states and understand the physical conditions necessary for the formation of relativistic jets.Coordinated x-ray, optical, IR, and radio observations of other Galactic rela-tivistic jet sources: These observations will include the astronomical sources GRO J1655-40, Cyg X-3, XTE J1748-288, SS 433, CI Cam, and LSI +61 303. The comparison of the observational data between these objects and with GRS 1915+105 will provide insights into the origin and nature of relativistic jets in Galactic X-ray binaries.Long-term IR monitoring of microquasars using Cornell's 0.6-m telescope and a new IR array camera: This type of monitoring, which has not been possible previously, will allow measurement of binary periods and recurrence timescales of IR flaring. Undergraduate students will carry out this work in the summer months and results of the research will be incorporated into the existing undergraduate astronomy laboratory classes during the academic year.Development and implementation of strategies for identifying new microquasar systems: This effort will include the study of candidate IR counterparts for the microquasars lE 1740-29 and GRS 1758-258, which were discovered using deep IR images from the Keck 10-m telescopes.The educational effort will include the training of undergraduate and graduate students. In addition, a laboratory curriculum will be developed and implemented for 5th-7th grade students, which emphasizes the fundamental importance of measurement to the scientific process. Key features include:Collaboration with the Ithaca City School District (ICSD) to develop basic hands- on experiments with links to current astronomical research. The goal is to help answer the question "How do we know what we know about the Universe?" The ICSD teachers will "field-test" the experiments and the results will be used to refine the experiments.Collaboration with the Cambridge Public Schools to develop a Spanish-language version of the laboratory and Web materials for use in bilingual classrooms. Field-testing of the Spanish version in Cambridge will also be used to refine the experiments. This component will provide an important means for outreach to historically underrepresented Spanish-speaking children.Development of Web-based resources which will allow students/teachers to explore the relationship between the results of their experiments and those of researchers working at the forefront of astrophysics. In the future, the resources will be made available nationwide to both English- and Spanish-speaking classrooms via the Internet.The Division of Astronomical Sciences provides support for this project.***

银河相对论喷射源的AST-9983830 Eikenberrymulti小波长研究 - 将进行“微Quasars”。该研究的总体目标是了解黑洞X射线二进制文件中相对论喷射的起源，形成和演变。 这些研究获得的知识将用于了解我们银河系中的黑洞/相对论射流系统及其在活性银河核中的较大类似物。 这项研究基于先前关于微Quasar GRS +105和其他微Quasar候选者的X射线和红外（IR）研究。 要进行的科学工作的亮点包括：在Microquasar GRS 1915-105中，相对论喷气形成的协调X射线，IR和无线电观察结果：先前对该对象的X射线/IR/无线电观察到该对象的先前协调，提供了第一个直接直接，在任何系统中提供了第一个直接的，TINE的相对组建的观测值。 这些和其他观察结果还表明，GRS 1915+105表现出许多不同的生产和非杰特生产行为的状态。 观察活动将有助于对这些状态进行分类，并了解形成相对论喷气机所需的物理条件。协调的X射线，光学，IR和无线电观察结果：这些观察结果将包括天文来源GRO J1655-40 +61 303。这些物体与GRS 1915 +105之间观察数据的比较将提供有关银河系X射线二进制中相对论喷气机的起源和性质的见解。长期的IR ir ir监测微型QuaSars对Microquasars进行了使用Cornell的0.6-m望远镜和新型IR摄像机的测量，以前允许该类型的摄像机： ir燃烧的时间尺度。本科生将在夏季进行这项工作，研究结果将在学年期间纳入现有的本科天文学实验室课程中。开发和实施识别新的微夸张系统的策略：这项工作将包括针对Microquasars Le 1740-29 and Grs 175-25的候选IR候选IR的研究研究望远镜的教育工作将包括对本科生和研究生的培训。此外，将为5至7年级的学生开发和实施实验室课程，这强调了测量对科学过程的基本重要性。 关键特征包括：与伊萨卡市学区（ICSD）合作开发基本的实验 - 与当前天文学研究链接的实验。目的是帮助回答“我们如何知道我们对宇宙的了解？” ICSD教师将“实地测试”实验，结果将用于完善实验。与剑桥公立学校进行集合制定，以开发西班牙语版本的实验室和网络材料，用于双语教室。 剑桥中西班牙版的现场测试也将用于完善实验。该组成部分将为历史上代表性不足的西班牙语儿童提供宣传的重要手段。基于Web的资源的开发将使学生/老师能够探索他们的实验结果与在天体物理学最前沿的研究人员之间的关系。 将来，资源将在全国范围内通过互联网提供给英语和西班牙语的教室。天文学科学的部门为该项目提供了支持。***
