Auriga-Explorer-Nautilus-Virgo合作的首次联合引力波搜索
First joint Gravitational Waves search by the Auriga-Explorer-Nautilus-Virgo collaboration
摘要：
我们目前的搜索结果，在2005年9月期间收集的AURIGA，EXPLORER，NAUTILUS和室女座探测器的24小时长的数据集的重合突发激发。对来自单个检测器的每个数据集独立地进行候选触发物的搜索。我们使用针对给定来源群体优化的算法寻找这些候选者之间的双重时间重合，并通过将模板化信号波形注入数据流来计算检测效率。为此，我们考虑了信号的情况下，阻尼正弦曲线来自银河系中心方向。在这个框架中，我们的方法的目标是高效率和低误报率之间的最佳平衡，旨在设置置信区间，尽可能严格的所选源模型的速率。
英文摘要：
We present results of the search for coincident burst excitations over a 24 hours long data set collected by AURIGA, EXPLORER, NAUTILUS and Virgo detectors during September 2005. The search of candidate triggers was performed independently on each of the data sets from single detectors. We looked for two-fold time coincidences between these candidates using an algorithm optimized for a given population of sources and we calculated the efficiency of detection through injections of templated signal waveforms into the streams of data. To this purpose we have considered the case of signals shaped as damped sinusoids coming from the galactic center direction. In this framework our method targets an optimal balance between high efficiency and low false alarm rate, aiming at setting confidence intervals as stringent as possible in terms of the rate of the selected source models.
