SN1987A期间引力波与中微子探测器关联的新分析
New analysis for the correlation between gravitational waves and neutrino detectors during SN1987A
摘要：
SN 1987 A仍然存在两个主要问题：a）引力波探测器观测到的信号，b）坍缩的持续时间。事实上，a）引力波探测器的灵敏度对于探测引力波来说似乎很小，b）虽然一些实验数据表明持续时间为几个小时，但大多数理论假设坍缩在几秒钟内发展。由于最近的X射线NuSTAR卫星的数据显示了一个明显的证据，不对称的崩溃，我们已经重新审视了实验数据记录的地下和引力波探测器运行期间SN 1987 A。新的证据表明，与RMS以前的结果，即运行在罗马和马里兰州的引力波探测器记录的数据与勃朗峰和神冈探测器的数据有很强的相关性，并在勃朗峰时间为中心的一个很长的时间（一个或两个小时）的相关性延伸。这一结果表明神冈德在勃朗峰时间也探测到了中微子，这些相互作用没有被识别出来，因为它们没有聚集在一个爆发中。
英文摘要：
Two major problems, still associated with the SN1987A, are: a) the signals observed with the gravitational waves detectors, b) the duration of the collapse. Indeed, a) the sensitivity of the gravitational wave detectors seems to be small for detecting gravitational waves and, b) while some experimental data indicate a duration of order of hours, most theories assume that the collapse develops in a few seconds. Since recent data of the X-ray NuSTAR satellite show a clear evidence of an asymmetric collapse, we have revisited the experimental data recorded by the underground and gravitational wave detectors running during the SN1987A. New evidence is shown that con rms previous results, namely that the data recorded by the gravitational wave detectors running in Rome and in Maryland are strongly correlated with the data of both the Mont Blanc and the Kamiokande detectors, and that the correlation extends over a long period of time (one or two hours) centered at the Mont Blanc time. This result indicates that also Kamiokande detected neutrinos at the Mont Blanc time, and these interactions were not identi ed because not grouped in a burst.
