Continued Post-Launch Support of XMM Newton in the UK: the XMM-Newton Survey Science Centre

XMM-牛顿测量科学中心（SSC）是一个国际合作项目，由英国、法国、德国、意大利和西班牙的10个机构组成。SSC在XMM-牛顿项目中发挥着重要的科学作用，包括：㈠开发和维护XMM-牛顿科学分析软件; ㈡对所有XMM-牛顿观测进行例行科学处理; ㈢ XMM-牛顿偶然调查的地面后续/识别方案; ㈣汇编XMM-牛顿源目录。这些活动在XMM-牛顿的科学成功中发挥了重要作用。举一个例子，XMM-牛顿偶然源目录提供了一个主要的资源，使天文学家能够探索天空中X射线发射物体的数量。其中包括一些目前已知的最奇特的物体，包括星系中心的超大质量黑洞，充满星系团之间空间的热气，具有热日冕的活跃恒星，由中子星星或黑洞吸积提供动力的双星系统，以及超新星爆炸的冲击加热气体残余物。

The XMM-Newton Survey Science Centre (SSC) is an international collaboration involving a consortium of 10 institutions in the UK, France, Germany, Italy and Spain. The SSC plays a major scientific role in the XMM-Newton project including: (i) the development and maintenance of the XMM-Newton science analysis software; (ii) the routine scientific processing of all XMM-Newton observations; (iii) the ground-based follow-up/identification programme for the XMM-Newton serendipitous survey; (iv) the compilation of the XMM-Newton Source Catalogues. These activities play an important role in the scientific success of XMM-Newton. To take one example, the XMM-Newton serendipitous source catalogues provide a major resource that enable astronomers to explore the population of X-ray emitting objects in the sky. These include some of the most exotic objects currently known, including supermassive black holes at the centres of galaxies, the hot gas that fills the space between the galaxies in clusters, dramatically active stars with hot coronae, binary systems powered by accretion onto a neutron star or black hole and the shock-heated gaseous remnants of supernova explosions.
