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-0507547艾肯伯里，斯蒂芬·弗洛里达大学致密天体的物理和起源的多波长研究将开展一项多波长观测活动，重点是微类星体和银河系内外致密天体的起源。具体的项目目标是：1)磁弹模型将在微类星体GRS 1915+105的基础上进一步发展和扩展。许多多波长方面(X射线、红外和射电光曲线、光谱演化、准周期振荡等)2)新的红外光谱、光度和偏振测量将由Gran Telescope和Canarias红外相机实验成像器获得(预计2005年10月第一次亮相)。这些高时间分辨率的观测将集中在GRS 1915+105上，但也包括其他微类星体。3)基特峰国家天文台4米望远镜的近红外测光和佛罗里达红外宇宙学和天体物理成像光谱仪的图像切片器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)将使用钱德拉X射线档案观测结合两个微米全天巡天数据来搜索新的微类星体系统。使用加拿大-法国-夏威夷望远镜和双子座的红外光谱将确认可能的双子座。还计划扩大搜索范围，使用佛罗里达多目标成像近红外Grism观测光谱仪-2获取银河系中心附近约5000个红外源的光谱。5)微类星体/致密天体的起源也将通过寻找河外X射线双星(特别是在星暴星系中)来探索，这些双星又可以与其母星系团的性质(年龄、金属丰度、质量函数等)相关联。以更好地理解致密物体的起源。
