摘要:

INTEGRAL硬X射线测量已被证明具有根本的重要性。INTEGRAL以其大视野和出色的灵敏度绘制了银河平面。如此硬的X射线快照,在一年的时间尺度上,整个银河系超出了过去和现在的窄视场掠入射X射线望远镜的能力。通过将INTEGRAL X射线测量扩展到更短的时间尺度,使得对瞬态X射线发射体的有效搜索成为可能。在超过15年的运行中,INTEGRAL天文台为我们提供了一个更清晰的硬X射线天空视图,并为从射频到伽马射线的许多后续活动提供了触发器。除了对整个天空的硬X射线源进行普查外,INTEGRAL还通过地球掩星机动对大规模宇宙X射线背景进行了独特的观测,这无疑将被载入X射线天文学的史册,作为该飞行任务对我们了解硬X射线天空的最突出贡献之一。

英文摘要:

The INTEGRAL hard X-ray surveys have proven to be of fundamental importance. INTEGRAL has mapped the Galactic plane with its large field of view and excellent sensitivity. Such hard X-ray snapshots of the whole Milky Way on a time scale of a year are beyond the capabilities of past and current narrow-FOV grazing incidence X-ray telescopes. By expanding the INTEGRAL X-ray survey into shorter timescales, a productive search for transient X-ray emitters was made possible. In more than fifteen years of operation, the INTEGRAL observatory has given us a sharper view of the hard X-ray sky, and provided the triggers for many follow-up campaigns from radio frequencies to gamma-rays. In addition to conducting a census of hard X-ray sources across the entire sky, INTEGRAL has carried out, through Earth occultation maneuvers, unique observations of the large-scale cosmic X-ray background, which will without question be included in the annals of X-ray astronomy as one of the mission's most salient contribution to our understanding of the hard X-ray sky.
