We propose four 80ksec observations of the black hole candidate Cyg X-1 simultaneous to our accepted XMM-Newton observations in the fall of 2004. The scientific aim of this campaign is to measure a high signal to noise spectrum of Cyg X-1 from 0.5 to above 600keV allowing us to constrain models for the Comptonizing plasma responsible for the hard X-ray spectrum to constrain the amount of Compton reflection in the system to provide the >10keV continuum above a possibly relativistically broadened Fe Kalpha line and to search for and study the effects of non-thermal Comptonization and/or synchrotron self-Compton emission from a jet.

我们计划对黑洞候选体天鹅座X-1（Cyg X-1）开展四次时长为80千秒的观测，该观测与我们2004年秋季已获批的XMM-牛顿（XMM-Newton）观测同步实施。本观测项目的科学目标为获取天鹅座X-1在0.5千电子伏至600千电子伏以上能段的高信噪比光谱，以此实现以下科学产出：约束产生硬X射线能谱的康普顿化等离子体模型；限定系统内康普顿反射的总量；在可能存在相对论展宽的铁Kα谱线之上获得10千电子伏以上的连续谱；搜寻并研究喷流产生的非热康普顿过程及/或同步辐射自康普顿辐射的效应。【内容已截断，请查阅原始数据集获取完整文本】
