论文摘要
XMM群集调查（XCS）开发了一个新的Python模块X射线：生成和分析（XGA），以提供XMM-Newton Space望远镜观察到的X射线发射源的交互式和自动分析。 XGA仅要求创建了一组清洁，处理，事件列表，并且（（可选））源检测器已经生成了观测值的区域列表。 XGA围绕使所有可用数据易于访问和分析的概念。用户在他们希望调查的来源上提供信息（例如RA，DEC，RedShift），XGA找到相关的观察值并生成所需的数据产品。这使用户可以使用所有相关观察结果快速，轻松地完成常见分析，因此可以自由专注于提取最大的科学收益。 XGA围绕源和示例类，这些类别代表不同类型的X射线发射天体物理对象，并且具有与该类型对象相关的不同属性和方法。 XGA还包含产品类，这些类别为X射线数据产品或信息（例如径向配置文件）提供了界面，并采用了内置方法，用于拟合，分析和可视化。 XGA可以与XSPEC拟合模型（全局和环形），测量频谱特性，例如温度，光子指数和光度。 XGA还可以测量星系簇的密度和温度的径向谱，从而可以测量GALAXY簇的气体和总质量分布。将来，我们将增加对XMM（例如Chandra，Erosita）以外的X射线望远镜的支持，以及执行多损耗关节分析的能力。随着新的X射线观测站的出现，例如Erosita，Xrism，Athena和Lynx，这是一个新的开源，开源的软件包的理想时机，可供任何人使用和仔细检查。
The XMM Cluster Survey (XCS) have developed a new Python module, X-ray: Generate and Analyse (XGA) to provide interactive and automated analyses of X-ray emitting sources observed by the XMM-Newton space telescope. XGA only requires that a set of cleaned, processed, event lists has been created, and (optionally) that a source detector has generated region lists for the observations. XGA is centered around the concept of making all available data easily accessible and analysable. The user provides information (e.g. RA, Dec, redshift) on the source they wish to investigate, and XGA locates relevant observations and generates required data products. This allows the user to quickly and easily complete common analyses using all relevant observations, thus being left free to focus on extracting the maximum scientific gain. XGA is centered around source and sample classes, which represent different types of X-ray emitting astrophysical objects and have different properties and methods relevant to that type of object. XGA also contains product classes, which provide interfaces to X-ray data products or information (such as radial profiles) that have been derived from them, with built-in methods for fitting, analysis, and visualisation. XGA can fit models to spectra (both global and annular) with XSPEC, measuring spectral properties such as temperature, photon index, and luminosity. XGA can also measure radial profiles of density and temperature for galaxy clusters, allowing the measurement of gas and total mass profiles of galaxy clusters. In the future, we will add support for X-ray telescopes other than XMM (e.g. Chandra, eROSITA), as well as the ability to perform multi-mission joint analyses. With the advent of new X-ray observatories such as eROSITA, XRISM, ATHENA, and Lynx, it is the perfect time for a new, open-source, software package that is open for anyone to use and scrutinise.
