在伽马射线暴和引力波信号之间的预期关联的框架内，我们提出了一个分析的初步结果，旨在寻找与长GRB 050915a相关的引力波爆发。雨燕卫星于2005年探测到GRB 050915a，当时室女座探测器正在进行其科学运行之一，即C7运行，在此期间显示出2005年达到的最佳灵敏度。这为伽马射线暴和室女座引力波探测器之间的首次重合分析提供了机会。在这里，我们给出了一个正在进行的分析，这在年底将发挥原型的作用，至关重要的定义方法的伽玛射线暴触发搜索处女座的概述。我们分析的最终结果还将使我们能够评估Virgo能够将来自典型长伽马射线爆发的引力波信号的振幅限制到何种程度。
In the framework of the expected association between gamma-ray bursts and gravitational wave signals, we present the preliminary results of an analysis aimed to search for bursts of gravitational waves associated with the long GRB 050915a. GRB 050915a was detected by the Swift satellite in 2005, when the Virgo detector was engaged in one of its science runs, namely the C7 run, during which the best sensitivity attained in 2005 was exhibited. This offered the opportunity for the first coincident analysis between a gamma-ray burst and the Virgo gravitational wave detector. Here we give an overview of this ongoing analysis, which at the end will play the role of a prototype, crucial in defining a methodology for gamma-ray burst triggered searches with Virgo. The final results of our analysis will also allow us to evaluate up to which level Virgo will be able to constrain the amplitude of the gravitational wave signal from a typical long gamma-ray burst.
