XIM:一个用于流体动力学模拟的虚拟X射线观测站

XIM: A virtual X-ray observatory for hydrodynamic simulations

S. Heinz, M. Brüggen

摘要:

我们提出了一个描述的公共代码XIM,一个虚拟的X射线天文台。XIM可用于将天体物理对象的流体动力学模拟转换为虚拟X射线观测,以便与观测结果直接比较,并使用标准X射线分析工具进行后处理,这些天体包括大尺度结构、星系团、星系群、超新星遗迹和类似的扩展天体。默认情况下,XIM模拟钱德拉和国际X射线天文台(IXO),但可以适应任何用户指定的望远镜参数和仪器响应。XIM应用的例子包括来自星系团中AGN反馈的模拟X射线腔的虚拟钱德拉成像,星系团速度场的运动学映射(例如,由于合并或活动星系核反馈),以及来自空间等离子体的多相、多温度光谱的详细光谱建模。

英文摘要:

We present a description of the public code XIM, a virtual X-ray observatory. XIM can be used to convert hydrodynamic simulations of astrophysical objects, such as large scale structure, galaxy clusters, groups, galaxies, supernova remnants, and similar extended objects, into virtual X-ray observations for direct comparison with observations and for post-processing with standard X-ray analysis tools. By default, XIM simulates Chandra and the International X-ray Observatory (IXO), but can accommodate any user-specified telescope parameters and instrument responses. Examples of XIM applications include virtual Chandra imaging of simulated X-ray cavities from AGN feedback in galaxy clusters, kinematic mapping of cluster velocity fields (e.g., due to mergers or AGN feedback), as well as detailed spectral modeling of multi-phase, multi-temperature spectra from space plasmas.
