Abstract

Baikal-GVD is a cubic kilometer-scale neutrino detector currently under construction in Lake Baikal, Russia. The detector has been taking scientific data in partial configurations since 2016 and is now 70% complete. We present a search for astrophysical point-like neutrino sources using a 5-year track-like event dataset collected by Baikal-GVD in 2019–2024 yr. No significant neutrino source has been found in this analysis. Therefore we compute upper limits for a selection of candidate objects. The results are compared to published results from IceCube, ANTARES and KM3NeT.

用Baikal-GVD寻找类点中微子源

贝加尔湖- gvd是一个立方公里规模的中微子探测器，目前正在俄罗斯贝加尔湖建设中。自2016年以来，该探测器一直在部分配置中采集科学数据，目前已完成70%。我们利用贝加尔湖gvd在2019-2024年间收集的5年轨道状事件数据集，对天体物理点状中微子源进行了搜索。在此分析中没有发现重要的中微子源。因此，我们计算候选对象选择的上限。结果与IceCube、ANTARES和KM3NeT公布的结果进行了比较。
