Abstract

The Advanced X-ray Imaging Satellite (AXIS) promises revolutionary science in the X-ray and multi-messenger time domain. AXIS will leverage excellent spatial resolution (<1.5 arcsec), sensitivity (80× that of Swift), and a large collecting area (5–10× that of Chandra) across a 24-arcmin diameter field of view at soft X-ray energies (0.3–10.0 keV) to discover and characterize a wide range of X-ray transients from supernova-shock breakouts to tidal disruption events to highly variable supermassive black holes. The observatory’s ability to localize and monitor faint X-ray sources opens up new opportunities to hunt for counterparts to distant binary neutron star mergers, fast radio bursts, and exotic phenomena like fast X-ray transients. AXIS will offer a response time of <2 h to community alerts, enabling studies of gravitational wave sources, high-energy neutrino emitters, X-ray binaries, magnetars, and other targets of opportunity. This white paper highlights some of the discovery science that will be driven by AXIS in this burgeoning field of time domain and multi-messenger astrophysics. This White Paper is part of a series commissioned for the AXIS Probe Concept Mission; additional AXIS White Papers can be found at the AXIS website.

AXIS 时域和多信使科学的前景

先进 X 射线成像卫星（AXIS）有望在 X 射线和多信使时域实现革命性的科学研究。AXIS 将在软 X 射线能量（0.3-10.0 千伏）下的 24 弧分直径视场中，利用出色的空间分辨率（<1.5 弧秒）、灵敏度（是 Swift 的 80 倍）和较大的收集面积（是 Chandra 的 5-10 倍），发现并描述从超新星震荡爆发到潮汐破坏事件再到高度可变的超大质量黑洞等各种 X 射线瞬变现象。该天文台定位和监测微弱 X 射线源的能力为寻找遥远的双中子星合并、快速射电暴以及快速 X 射线瞬变等奇异现象的对应物提供了新的机会。AXIS 对社区警报的响应时间将小于 2 小时，从而能够对引力波源、高能中微子发射器、X 射线双星、磁星和其他机会目标进行研究。本白皮书重点介绍了 AXIS 将在这一新兴的时域和多信使天体物理学领域推动的一些发现科学。本白皮书是 AXIS 探测器概念任务委托编写的系列白皮书之一；其他 AXIS 白皮书可在 AXIS 网站上查阅。
