论文摘要
正在进行的大规模光学时间域调查（例如Zwicky Transient设施（ZTF））以前所未有的速度生产警报。到目前为止，对瞬态源的分析已经遵循了两种不同的路径：在不再可观察到的瞬态源数据的档案分析和在首次检测到源时的实时分析的时候。后者是警报经纪人的领域，例如亚利桑那州 - 诺拉布的时间分析和对事件系统（Antares）的响应。在本文中，我们综合了两种分析路径，并提出了对档案警报传播数据的首次系统研究，重点是在ZTF警报的Antares档案中鉴定出的多言式光曲线外乳流瞬变。我们的分析得出了37个这样的来源的样本，包括核心差的超新星（具有两个类似IPTF14HL），热核超新星与周围的杂物介质相互作用，潮汐破坏事件，发光的蓝色变量以及尚未分类的对象。目前，确定的资源很大一部分是活跃的，需要在不久的将来分配后续资源，以进一步限制其性质和工作过程。
Ongoing large-scale optical time-domain surveys, such as the Zwicky Transient Facility (ZTF), are producing alerts at unprecedented rates. Analysis of transient sources has so far followed two distinct paths: archival analysis of data on transient sources at a time when they are no longer observable and real-time analysis at the time when the sources are first detected. The latter is the realm of alert brokers such as the Arizona-NOIRLab Temporal Analysis and Response to Events System (ANTARES). In this paper, we synthesize the two analysis paths and present a first systematic study of archival alert-broker data, focusing on extragalactic transients with multipeaked light curves identified in the ANTARES archive of ZTF alerts. Our analysis yields a sample of 37 such sources, including core-collapse supernovae (with two analogs of iPTF14hls), thermonuclear supernovae interacting with their surrounding circumstellar medium, tidal disruption events, luminous blue variables, and as yet unclassified objects. A large fraction of the identified sources is currently active, warranting allocation of follow-up resources in the immediate future to further constrain their nature and the physical processes at work.
