摘要

利用兹威基瞬变设施(ZTF)和其他天文台，我们确定了三个候选潮汐破坏事件(TDEs)，它们与冰立方探测到的高能中微子在空间和时间上是一致的:AT2019dsg, AT2019fdr和AT2019aalc。这三个事件都被证明能够产生高能中微子。在这些程序中，我将给出潮汐破坏事件的概述，概述我们与ZTF的后续计划，描述对每个巧合事件进行的观察，并强调它们的异同。

Multi-messenger observations of Tidal Disruption Events

Using the Zwicky Transient Facility (ZTF) and other observatories, we have identified three candidate Tidal Disruption Events (TDEs) in spatial and temporal coincidence with high-energy neutrinos detected by IceCube: AT2019dsg, AT2019fdr and AT2019aalc. All three of these events have been shown to be able to produce high-energy neutrinos. In these proceedings, I will give an overview of Tidal Disruption Events, outline our follow-up program with ZTF, describe the observations carried out for each of those coincident events and highlight their similarities and differences.
