我们给出了在2007年和2011年用光学方法观测到的两颗核心塌缩超新星引力波爆发的结果。我们使用了来自激光干涉仪引力波观测站、处女座引力波观测站和GEO 600型引力波观测站的数据。选择目标核心塌陷超新星的依据是：(1)距离近(约15Mpc)，(2)对核心塌陷时间的观测约束严格，确定了引力波搜索窗口，以及(3)核心塌陷时至少两个干涉仪的一致操作。我们没有找到合理的引力波候选者。我们给出了从天体物理良好动机和更具推测性的引力波发射机制探测到信号的概率，作为距离地球距离的函数，并讨论了升级后的高级LIGO和室女座探测器对探测来自核心塌缩超新星的引力波的影响。
We present results from a search for gravitational-wave bursts coincident with two core-collapse supernovae observed optically in 2007 and 2011. We employ data from the Laser Interferometer Gravitational-wave Observatory (LIGO), the Virgo gravitational-wave observatory, and the GEO 600 gravitational-wave observatory. The targeted core-collapse supernovae were selected on the basis of (1) proximity (within approximately 15 Mpc), (2) tightness of observational constraints on the time of core collapse that defines the gravitational-wave search window, and (3) coincident operation of at least two interferometers at the time of core collapse. We find no plausible gravitational-wave candidates. We present the probability of detecting signals from both astrophysically well-motivated and more speculative gravitational-wave emission mechanisms as a function of distance from Earth, and discuss the implications for the detection of gravitational waves from core-collapse supernovae by the upgraded Advanced LIGO and Virgo detectors.
