摘要:

意大利新硬X射线飞行任务旨在为一些热点天体物理问题提供真正的突破,这些问题包括:黑洞普查、吸积物理学、粒子加速机制、高度磁化等离子体中的辐射转移效应和强引力场。NHXM是HEXIT-Sat概念的演变,它结合了高达80 keV的精细成像能力,目前仅在E<10 keV时可用,具有灵敏的光电成像偏振测量。它由四个相同的镜子组成,焦距为10米,发射后通过一个可展开的结构实现。四个望远镜中的三个将在其焦点上安装相同的光谱成像相机,而X射线成像偏振相机将安装在第四个望远镜的焦点上。为了确保低而稳定的背景,NHXM将被置于近地赤道轨道。在本文中,我们提供了一个全面的描述,这是目前在B阶段的任务。

英文摘要:

The Italian New Hard X-ray Mission (NHXM) has been designed to provide a real breakthrough on a number of hot astrophysical issues that includes: black holes census, the physics of accretion, the particle acceleration mechanisms, the effects of radiative transfer in highly magnetized plasmas and strong gravitational fields. NHXM is an evolution of the HEXIT-Sat concept and it combines fine imaging capability up to 80 keV, today available only at E<10 keV, with sensitive photoelectric imaging polarimetry. It consists of four identical mirrors, with a 10 m focal length, achieved after launch by means of a deployable structure. Three of the four telescopes will have at their focus identical spectral-imaging cameras, while X-ray imaging polarimetric cameras will be placed at the focus of the fourth. In order to ensure a low and stable background, NHXM will be placed in a low Earth equatorial orbit. In this paper we provide an overall description of this mission that is currently in phase B.
