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，对紧凑型物理学和起源的Floridamultibegents研究的StepheNuniversity将集中于微量词，并集中于微量词，并集中于我们星系中紧凑型物体的起源。目的是从这种系统中更好地理解相对论的喷气机 - 它们的形成和发展方式。特定的项目目标是：1）磁性炸弹模型将根据Themicroquasar Grs 1915+105进一步开发和扩展。将对许多多波长方面（X射线，红外，Andradio光曲线，光谱进化，准周期性振荡等）进行兼容和测试。2）新的红外光谱，光度法和极化型将使用Gran望远镜和CanaRares Infrared Infrared Experiment Imperiment Imperiment（Acctectife）获得。这些高度分辨率的观察结果将集中于1915+105，但还包括其他微Quasars。 3）与基特峰国家观测站4米望远镜和用于红外宇宙学和天体物理图像图的佛罗里达州图像切片机相近的IR光学测定法将近乎限制模型。观察结果与两个微米的所有天空调查数据相结合。可能会使用加拿大 - 弗朗西·霍瓦伊望远镜和双子座的红外光谱证实可能的剂量剂。还计划在银河系中心附近使用佛罗里达多物体观察光谱仪-2的搜索扩展以获得〜5000个红外源的光谱。 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.
