下一次核心坍塌的超新星(SN)在我们的银河系爆炸时，各种探测器将准备就绪，等待着探测它发出的引力波(GW)和中微子。目前的数值模拟已经成功地引入了多维效应来产生爆炸SN模型，但到目前为止对爆炸机理还不是很清楚。在本文中，我们通过比较GW辐射和中和爆发的开始时间来研究前驱体核的自转。假设GW探测器和中微子探测器分别是KAGRA探测器和共置的Gd负载水Cherenkov探测器，要么是GADS，要么是Gadzook！我们的探测模拟研究表明，对于附近的SN(0.2KPC)，我们几乎100%的时间可以确认没有核心旋转，大约90%的时间可以确认核心旋转的存在。使用这种方法，也有可能确认更远的银河系SN爆炸的旋转。
The next time a core-collapse supernova (SN) explodes in our galaxy, various detectors will be ready and waiting to detect its emissions of gravitational waves (GWs) and neutrinos. Current numerical simulations have successfully introduced multi-dimensional effects to produce exploding SN models, but thus far the explosion mechanism is not well understood. In this paper, we focus on an investigation of progenitor core rotation via comparison of the start time of GW emission and that of the neutronization burst. The GW and neutrino detectors are assumed to be, respectively, the KAGRA detector and a co-located gadolinium-loaded water Cherenkov detector, either EGADS or GADZOOKS!. Our detection simulation studies show that for a nearby SN (0.2 kpc) we can confirm the lack of core rotation close to 100% of the time, and the presence of core rotation about 90% of the time. Using this approach there is also the potential to confirm rotation for considerably more distant Milky Way SN explosions.
