论文摘要
我们介绍了低到中间红移（$ 0 \ le z \ le 1 $）瞬变的X射线相空间的详细汇编和分析，该瞬变巩固了0.3---10 KeV能量频段中各种类多种瞬态/可变现象的观察到的光曲线（和理论）。 We include gamma-ray burst afterglows, supernovae, supernova shock breakouts and shocks interacting with the environment, tidal disruption events and active galactic nuclei, fast blue optical transients, cataclysmic variables, magnetar flares/outbursts and fast radio bursts, cool stellar flares, X-ray binary outbursts, and ultraluminous X-ray sources.我们的总体目标是为检查这些短暂事件提供全面的资源，从而扩展了X射线持续时间 - 轻度相位空间（DLP）以显示亮度演变。我们使用现有的观测值（靶向和偶然性）来表征各种瞬态/可变种群的行为。较大DLP中的瞬态信号的上下文将瞬态信号用于两个主要目的：确定感兴趣的领域（即参数空间中的区域，其中一个人会期望检测，但是在历史上缺乏观察值）并为对新发现的瞬态信号进行分类时提供了最初的定性指导。我们发现，虽然相位空间中最具发光性最高（主要是银河系）和最小发光（很大的银河系）的一部分在$ t> 0.1 $ days中，但中等亮度现象（l $ _x = 10^{34} -10^{34} -10^{34} -10^{42} {42} $ ERG S $^S $^{ - 1} $表示阶段。因此，我们确定l $ _x = 10^{34} -10^{42} $ erg s $^{ - 1} $和$ t = 10^{ - 4} - 0.1 $ days作为瞬态X射线X射线天文学中的关键发现阶段。
We present a detailed compilation and analysis of the X-ray phase space of low- to intermediate-redshift ($ 0\le z \le 1$) transients that consolidates observed light curves (and theory where necessary) for a large variety of classes of transient/variable phenomena in the 0.3--10 keV energy band. We include gamma-ray burst afterglows, supernovae, supernova shock breakouts and shocks interacting with the environment, tidal disruption events and active galactic nuclei, fast blue optical transients, cataclysmic variables, magnetar flares/outbursts and fast radio bursts, cool stellar flares, X-ray binary outbursts, and ultraluminous X-ray sources. Our overarching goal is to offer a comprehensive resource for the examination of these ephemeral events, extending the X-ray duration-luminosity phase space (DLPS) to show luminosity evolution. We use existing observations (both targeted and serendipitous) to characterize the behavior of various transient/variable populations. Contextualizing transient signals in the larger DLPS serves two primary purposes: to identify areas of interest (i.e., regions in the parameter space where one would expect detections, but in which observations have historically been lacking) and to provide initial qualitative guidance in classifying newly discovered transient signals. We find that while the most luminous (largely extragalactic) and least luminous (largely Galactic) part of the phase space is well-populated at $t > 0.1$ days, intermediate luminosity phenomena (L$_x = 10^{34} - 10^{42}$ erg s$^{-1}$) represent a gap in the phase space. We thus identify L$_x = 10^{34} - 10^{42}$ erg s$^{-1}$ and $t = 10^{-4} - 0.1$ days as a key discovery phase space in transient X-ray astronomy.
