Abstract

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 in the 0.3-10 keV band across a 450 arcminute2 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.

先进x射线成像卫星(AXIS)概述

先进x射线成像卫星(AXIS)是一个探测器级的概念，它将建立在钱德拉x射线天文台的遗产上，通过450弧分2视场提供低背景，弧秒分辨率为0.3-10 keV的波段，灵敏度提高了一个数量级。AXIS在单晶硅轻质分段x射线光学元件的构建方面取得了突破，并在具有良好光谱分辨率的大画幅、小像素、高读出率CCD探测器的制造方面取得了进展，从而实现了稳健且经济高效的设计。此外，AXIS将对目标机会警报做出响应，并配有机载瞬态探测，将成为研究随时间变化的x射线宇宙的强大设备，继承了尼尔·格雷斯(Swift) x射线天文台的遗产，该天文台彻底改变了瞬态x射线宇宙的研究。在本文中，我们介绍了AXIS的概述，突出了驱动AXIS概念的主要科学目标以及天文台设计将如何实现这些目标。
