摘要：
先进X射线成像卫星（AXIS）是一个Probe级概念，它将继承钱德拉X射线天文台的遗产，在0.3-10 keV能段、450平方角分的视场内提供低背景、角秒级分辨率的成像，灵敏度提升一个数量级。AXIS利用单晶硅轻量化分段X射线光学制造方面的突破，以及大规格、小像素、高读出率、具有良好光谱分辨率的CCD探测器制造进展，实现了稳健且具有成本效益的设计。此外，AXIS将响应机会目标警报，并具备星上瞬变源探测能力，将成为研究时变X射线宇宙的强大设施，延续尼尔·格雷尔斯（雨燕）X射线天文台的遗产，该天文台曾彻底改变了瞬变X射线宇宙的研究。在本文中，我们概述了AXIS，重点介绍驱动AXIS概念的首要科学目标，以及天文台设计将如何实现这些目标。
英文摘要：
The Advanced X-ray Imaging Satellite (AXIS) is a Probe-class concept that will build on the legacy of the Chandra X-ray Observatory by providing low-background, arcsecond-resolution imaging in the 0.3-10 keV band across a 450 arcminute$^2$ field of view, with an order of magnitude improvement in sensitivity. AXIS utilizes breakthroughs in the construction of lightweight segmented X-ray optics using single-crystal silicon, and developments in the fabrication of large-format, small-pixel, high readout rate CCD detectors with good spectral resolution, allowing a robust and cost-effective design. Further, AXIS will be responsive to target-of-opportunity alerts and, with onboard transient detection, will be a powerful facility for studying the time-varying X-ray universe, following on from the legacy of the Neil Gehrels (Swift) X-ray observatory that revolutionized studies of the transient X-ray Universe. In this paper, we present an overview of AXIS, highlighting the prime science objectives driving the AXIS concept and how the observatory design will achieve these objectives.
