摘要:

正在进行的大规模光时域调查,如Zwicky瞬态设施(ZTF),正在以前所未有的速度发出警报。瞬态源的分析迄今为止遵循两种不同的路径:在瞬态源不再可观察时对瞬态源数据进行存档分析,以及在首次检测到瞬态源时进行实时分析。后者是警报经纪人的领域,如Arizona-NOIRLab时间分析和对事件的反应系统(ANTARES)。在本文中,我们综合了这两个分析路径,并提出了第一个系统的研究档案警报经纪人数据,集中在河外瞬变与多峰光变曲线中确定的ANTARES档案的ZTF警报。我们的分析产生了37个这样的来源,包括核心坍缩超新星(与iPTF 14 hls的两个类似物),热核超新星与周围的星周介质相互作用,潮汐破裂事件,明亮的蓝色变量,以及尚未分类的对象。大部分已查明的来源目前仍在活动中,因此在不久的将来无法分配后续资源,以进一步限制其性质和实际工作过程。

英文摘要:

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.
