我们证明，在未来的10赫兹干涉仪上观测到核心塌缩超新星的引力记忆，可以在Mt级探测器上进行超新星中微子的时间触发搜索。在f(Cid：39)0时对特征菌株的敏感度至少为∼10−25。3赫兹-例如，通过将DECIGO的噪声提高一个数量级-将允许在距离D∼40−300MPC处的超新星的强大的时间触发，导致每十年运行的∼3−70中微子事件的几乎无背景的样本。这个样本将弥合罕见的银河系超新星爆发和宇宙学diff使用超新星中微子背景之间的灵敏度差距，使我们能够详细研究局部宇宙中超新星的中微子发射。
We demonstrate that observations of the gravitational memory from core collapse supernovae at future Deci-Hz interferometers enable time-triggered searches of supernova neutrinos at Mt-scale detectors. Achieving a sensitivity to characteristic strains of at least ∼ 10 − 25 at f (cid:39) 0 . 3 Hz – e.g., by improving the noise of DECIGO by one order of magnitude – will allow robust time triggers for supernovae at distances D ∼ 40 − 300 Mpc, resulting in a nearly background-free sample of ∼ 3 − 70 neutrino events per Mt per decade of operation. This sample would bridge the sensitivity gap between rare galactic supernova bursts and the cosmological diffuse supernova neutrino background, allowing detailed studies of the neutrino emission of supernovae in the local Universe.
