中微子可以在核心坍缩过程中探测恒星内部，有助于了解坍缩的不同阶段和过程。迄今为止，只从SN1987A这一单一事件中检测到超新星中微子。从那时起，大多数研究都集中在两个极端距离上；星系/本地超新星和所有过去的宇宙超新星形成弥漫性超新星中微子背景。我们专注于中距离状态，作为下一代探测器（如hyper -神冈探测器）探测核心坍缩超新星中微子的目标。为了量化中微子探测的重要性，我们利用了对近星系的调查以及大型天气调查的预期发现，以监测核心坍缩超新星的光学对应物。我们发现，探测前景需要大约十年的操作。我们讨论了电磁测量如何将核心坍缩时间精确到小时的时间尺度是自信的中微子探测的关键。像DLT40这样的瞬态巡天经常观测附近的星系，可以帮助我们获得这些关键信息。
Neutrinos allow the probing of stellar interiors during core collapse, helping to understand the different stages and processes in the collapse. To date, supernova neutrinos have only been detected from a single event, SN1987A. Most studies from then on have focused on two distance extremes; Galactic/local supernovae and all past cosmic supernovae forming the diffuse supernova neutrino background. We focus on the intermediate distance regime as a target for detecting core-collapse supernova neutrinos at next generation detectors like Hyper-Kamiokande. To quantify the significance of neutrino detections, we draw on expected discoveries by surveys of near galaxies as well as large synoptic surveys to monitor for optical counterparts of core-collapse supernovae. We find that detection prospects require approximately ten years of operation. We discuss how the ability of electromagnetic surveys to pinpoint the time of core collapse to within the timescale of hours is key for confident neutrino detections. Transient surveys like DLT40 which frequently observe nearby galaxies can help with such crucial information.
