摘要:

SuperAGILE是AGILE伽马射线飞行任务的硬X射线监测器,自2007年4月23日$^{rd}$起在轨运行。这是一个成像实验的基础上,一套四个独立的硅条探测器,配备了一维编码掩模,在标称能量范围18-60千电子伏。SuperAGILE的主要目标是与主要的伽马射线AGILE实验-伽马射线成像探测器-同时观测宇宙源。鉴于其$\sim$球面度宽的视野和$\sim$ 15 mCrab日灵敏度,SuperAGILE也非常适合长期监测银河系致密天体和探测明亮瞬变。SuperAGILE探测器的属性和设计允许在天体坐标的两个独立正交投影中的每一个中具有6弧分角分辨率。通过实验遥测,可连续获得逐个光子的数据,并将其用于导出各个源的图像和通量,积分时间取决于源的强度和视场中的位置。在本文中,我们报告了SuperAGILE在轨道上的头两年中取得的主要科学成果,直到2009年4月。

英文摘要:

SuperAGILE is the hard X-ray monitor of the AGILE gamma ray mission, in orbit since 23$^{rd}$ April 2007. It is an imaging experiment based on a set of four independent silicon strip detectors, equipped with one-dimensional coded masks, operating in the nominal energy range 18-60 keV. The main goal of SuperAGILE is the observation of cosmic sources simultaneously with the main gamma-ray AGILE experiment, the Gamma Ray Imaging Detector (GRID). Given its $\sim$steradian-wide field of view and its $\sim$15 mCrab day-sensitivity, SuperAGILE is also well suited for the long-term monitoring of Galactic compact objects and the detection of bright transients. The SuperAGILE detector properties and design allow for a 6 arcmin angular resolution in each of the two independent orthogonal projections of the celestial coordinates. Photon by photon data are continuously available by the experiment telemetry, and are used to derive images and fluxes of individual sources, with integration times depending on the source intensity and position in the field of view. In this paper we report on the main scientific results achieved by SuperAGILE over its first two years in orbit, until April 2009.
