标题： Search for Neutrinos from Populations of Optical Transients

摘要： 自2013年冰立方中微子天文台探测到高能宇宙中微子以来，科学家一直在寻找这些中微子流的起源。尽管最近有证据表明耀变星系可能是中微子的来源之一，但冰立方观测到的大部分弥漫性中微子流仍无法解释。 本文介绍了最新的冰立方实验结果，这些结果测试了中微子与潮汐瓦解事件（TDEs）之间的时间相关性，并限制了喷流型和非喷流型TDEs对弥漫天体物理中微子通量的贡献分别低于1.3%和26%（置信水平为90%）。此外，还展示了针对AT2018cow这一非凡瞬态现象中微子的专门搜索，并推导出中微子发射的上限。同时，还介绍了来自新的和即将开展的时间域光学巡天（如ZTF和LSST）的预期改进。 显示英文摘要

摘要： Since the detection of high-energy cosmic neutrinos at the IceCube Neutrino Observatory in 2013, there has been an on-going search to find the origins of this flux. Despite recent evidence identifying a flaring blazar as a possible neutrino source, the vast majority of the diffuse neutrino flux measured by IceCube remains unexplained. Here, the latest IceCube results testing time-dependent correlation between neutrinos and Tidal Disruption Events (TDEs) are presented, limiting the contribution of jetted and non-jetted TDEs to the diffuse astrophysical neutrino flux to be less than 1.3% and 26% respectively at 90% confidence level. In addition, a dedicated search for neutrinos from the extraordinary transient AT2018cow are presented, and upper limits on the integrated neutrino emission are derived. Expected improvements from new and upcoming time domain optical surveys (such as ZTF and LSST) are also introduced.
