论文摘要
由Icecube发现的高能天体中微子的起源仍然很大未知。多通用剂研究表明,这些中微子大多数来自伽马射线销售。窒息射流超新星(CJSNE)是由相对论喷射动力的超新星,在恒星材料中停滞不前,可能导致通过摄影相互作用进行中微子的发射,而相关的伽马射线被吸收。在本文中,我们执行了无链接的最大样品分析,以搜索Icecube十年的MUON轨道事件与我们的SN IB/C样本之间的相关性,这些相关性是从公开可用的目录中收集的。除了传统的幂律模型外,我们还首次考虑了更逼真的中微子发射模型的影响,我们研究了喷气光束因子在分析中的影响。我们的结果显示没有显着相关性。即便如此,我们设定了CJSNE对弥漫性天体中微子通量的贡献的保守上限仍然使SNE IB/C是IceCube观察到的天体中微子的主要来源。我们从我们的结果以及未来中微子和超新星观察的力量中讨论了对CJSNE场景的影响。
The origin of the high-energy astrophysical neutrinos discovered by IceCube remains largely unknown. Multimessenger studies have indicated that the majority of these neutrinos come from gamma-ray-dark sources. Choked-jet supernovae (cjSNe), which are supernovae powered by relativistic jets stalled in stellar materials, may lead to neutrino emission via photohadronic interactions while the coproduced gamma rays are absorbed. In this paper, we perform an unbinned maximum-likelihood analysis to search for correlations between IceCube's ten-year muon-track events and our SN Ib/c sample, collected from publicly available catalogs. In addition to the conventional power-law models, we also consider the impacts of more realistic neutrino emission models for the first time, and we study the effects of the jet beaming factor in the analyses. Our results show no significant correlation. Even so, the conservative upper limits we set to the contribution of cjSNe to the diffuse astrophysical neutrino flux still allow SNe Ib/c to be the dominant source of astrophysical neutrinos observed by IceCube. We discuss implications to the cjSNe scenario from our results and the power of future neutrino and supernova observations.
