AST-0507547Eikenberry, StephenUniversity of FloridaMultiwavelength Studies of the Physics and Origins of Compact ObjectsABSTRACTA multiwavelength observing campaign will be undertaken focused on microquasarsand the origins of compact objects in our Galaxy and beyond. The goal is to betterunderstand the relativistic jets from such systems - both how they form and evolve.Specific project goals are:1) The magnetic bomb model will be further developed and extended based on themicroquasar GRS 1915+105. Many multi-wavelength aspects (X-ray, infrared, andradio light curves, spectral evolution, quasi periodic oscillations, etc.) will beincorporated and tested.2) New infrared spectroscopy, photometry, and polarimitry will be obtained with TheGran Telescopio and The Canarias Infrared Camera Experiment imager (first lightexpected in Oct. 2005). These high time resolution observations will concentrate onGRS 1915+105, but also include other microquasars. The new observations willfurther constrain the models.3) Near IR-photometry with the Kitt Peak National Observatory 4-meter telescope andthe Florida image slicer for infrared cosmology and astrophysics imagingspectrograph will be used to explore the environments of microquasars and possibleinteractions, including possible termination shocks.4) A search for new microquasar systems will be undertaken using Chandra X-rayarchive observations combined with Two Micron All Sky Survey data. Possiblecandidates will be confirmed using infrared spectroscopy from the Canada-France-Hawaii Telescope and Gemini. An extension of the search to use The Florida MultiobjectImaging Near-IR Grism Observational Spectrometer-2 to obtain spectra of~5000 infrared sources near the Galactic center is also planned. Some 200-300 newX-ray binaries are expected to be found, doubling the number of known systems.5) The origins of microquasars/compact objects will also be explored through searchesfor extragalactic X-ray binaries (particularly in starburst galaxies) which can in turnbe correlated with properties of their parent clusters (age, metallicity, mass function,etc.) to better understand the origins of compact objects.

AST-0507547Eikenberry，斯蒂芬佛罗里达大学致密天体物理和起源的多波长研究摘要多波长观测活动将重点关注微类星体以及我们银河系及其他地区致密天体的起源。目标是更好地理解此类系统的相对论性喷流——它们是如何形成和演化的。具体项目目标是：1）磁弹模型将在微类星体GRS 1915+105的基础上进一步开发和扩展。许多多波长方面（X 射线、红外、射电光曲线、光谱演化、准周期振荡等）将被纳入和测试。2) 新的红外光谱、光度测定和偏振学将通过格兰望远镜和加那利群岛获得红外相机实验成像仪（预计于 2005 年 10 月首次亮相）。这些高时间分辨率观测将集中在 GRS 1915+105，但也包括其他微类星体。新的观测结果将进一步限制模型。3）基特峰国家天文台4米望远镜和佛罗里达图像切片机的红外宇宙学和天体物理成像光谱仪的近红外光度测量将用于探索微类星体的环境和可能的相互作用，包括可能的终止激波.4) 将利用钱德拉 X 射线档案观测数据与两微米全天巡天数据相结合来寻找新的微类星体系统。可能的候选者将使用加拿大-法国-夏威夷望远镜和双子座的红外光谱进行确认。还计划扩展搜索范围，使用佛罗里达多目标成像近红外棱镜观测光谱仪-2 来获取银河系中心附近约 5000 个红外源的光谱。预计将发现约 200-300 个新的 X 射线双星，使已知系统的数量增加一倍。5) 微类星体/致密天体的起源也将通过搜索河外 X 射线双星（特别是在星暴星系中）来探索，这些双星可以Turnbe 与其母星团的属性（年龄、金属丰度、质量函数等）相关，以更好地了解致密天体的起源。
