Multiwavelength Studies of the Physics and Origins of Compact Objects

AST-0507547 Eikenberry，StephenUniversity of Florida致密天体物理学和起源的多波长研究摘要多波长观测活动将集中在微类星体和我们银河系及更远的致密天体的起源上。该项目的目标是更好地理解来自这类系统的相对论喷流--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的基础上进一步发展和扩展。许多多波长方面（X射线、红外线、射电光变曲线、光谱演化、准周期振荡等）2）新的红外光谱学、光度学和偏振学将通过大望远镜和加那利红外照相机实验成像仪（2005年10月首次观测）获得。这些高时间分辨率观测将集中在GRS 1915+105上，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）利用基特峰国家天文台4米望远镜和佛罗里达红外宇宙学和天体物理学成像光谱仪的近红外测光来探索微类星体的环境和可能的相互作用。包括可能的终止冲击。4）将使用钱德拉X-射线档案观测结合两微米全天巡天数据。可能的候补星将使用加拿大-法国-夏威夷望远镜和双子座的红外光谱进行确认。还计划扩大搜索范围，使用佛罗里达多目标成像近红外光栅观测光谱仪-2获得银河系中心附近约5000个红外源的光谱。预计将发现大约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。来更好地理解紧凑物体的起源。

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.
