摘要:

EXTraS项目(探索X射线瞬变和可变天空)将收集迄今为止尚未探索的时间域信息,这些信息隐藏在欧空局XMM-牛顿X射线观测站上的欧洲光子成像照相机仪器自发射以来收集的偶然数据中。这将包括搜索快速瞬变,以及搜索和表征的变化(周期性和非周期性)在数十万源跨越超过九个数量级的时间尺度和六个数量级的流量。X射线结果将得到新发现的多波长表征的补充。还将进行可变源的现象学分类。我们的所有结果都将提供给社区。还将在意大利、德国和英国的选定高中实施教学计划。EXTraS项目(2014-2016年)由欧盟/FP 7框架内资助,由INAF(意大利),IUSS(意大利),CNR/IMATI(意大利),莱斯特大学(英国),MPE(德国)和ECAP(德国)合作开展。

英文摘要:

The EXTraS project (Exploring the X-ray Transient and variable Sky) will harvest the hitherto unexplored temporal domain information buried in the serendipitous data collected by the European Photon Imaging Camera (EPIC) instrument onboard the ESA XMM-Newton X-ray observatory since its launch. This will include a search for fast transients, as well as a search and characterization of variability (both periodic and aperiodic) in hundreds of thousands of sources spanning more than nine orders of magnitude in time scale and six orders of magnitude in flux. X-ray results will be complemented by multiwavelength characterization of new discoveries. Phenomenological classification of variable sources will also be performed. All our results will be made available to the community. A didactic program in selected High Schools in Italy, Germany and the UK will also be implemented. The EXTraS project (2014-2016), funded within the EU/FP7 framework, is carried out by a collaboration including INAF (Italy), IUSS (Italy), CNR/IMATI (Italy), University of Leicester (UK), MPE (Germany) and ECAP (Germany).
