'''女座干涉儀'''(Virgo({{lang-en|'''Virgo interferometer)interferometer'''}})是探測[[引力波|重力波]]的一個大型[[干涉儀]],位於[[義大利]][[比薩]]附近。女座干涉儀是一個隔離外部干擾[[迈克耳孙干涉仪]]:它的反射鏡和儀器被懸掛和激光束被在[[真空]]中運作。室女座干涉儀主要部分是兩個互相垂直的長臂,長度皆為3[[公里]]。
 
女座干涉儀由五個國家实验室的科学合作组织所組成:[[法國]]和義大利、[[荷蘭]]、[[波蘭]]與[[匈牙利]]。其他類似的干涉儀包含[[美國]][[雷射干涉重力波天文台]](LIGO)。自2007年以來,雷射干涉重力波天文台和女座干涉儀共享並共同分析偵測到的數據,並共同發表研究結果。這種合作是必要的:巨大的干涉探測器是不定向的(它們探測了整個天空),它們正在尋找哪些微弱的,很少發生的,並且埋沒于各種來源的儀器噪声的信號。因此,只有在多個儀器同時檢測的引力波才允許科學家聲稱得到一個發現,并且收集有關引力波信號的源的信息
 
女座干涉儀名稱來自[[室女座星系團]],它大約包含1,500個[[星系]],距離地球約5,000萬[[光年]]。因為室女座,是離地球最近的大型星系團,並且擁有[[雙星]]系統、[[中子星]]、[[黑洞]]、[[超新​​星]]爆炸等等有意思的可能波源因此觀測到重力波的機會較高。<ref name="CGShistory">

== 先进室女座探测器 ==
先进室女座干涉儀探测器旨在成為比初期室女座干涉儀探测器有10倍以上的敏感度。<ref>{{cite web|url=http://iopscience.iop.org/article/10.1088/0264-9381/32/2/024001 |title=Advanced Virgo: a second-generation interferometric gravitational wave detector - IOPscience |doi=10.1088/0264-9381/32/2/024001 |website=Iopscience.iop.org |date=2014-12-18 |accessdate=2016-02-11}}</ref>
 
一个先進室女座干涉儀的里程碑應該在2016年安裝的新探測器被達到。第一次與LIGO联合科學運行是在2016年下半年,接下来試運行期是幾個月。先進室女座干涉儀的全部設計靈敏度應在2018年實現。
處女座干涉儀由五個國家所組成:[[法國]]和義大利、[[荷蘭]]、[[波蘭]]與[[匈牙利]]。其他類似的干涉儀包含[[美國]][[雷射干涉重力波天文台]]。自2007年以來,雷射干涉重力波天文台和處女座干涉儀共享並共同分析偵測到的數據,並共同發表研究結果。
 
升級後的先進室女座干涉儀於2017年8月1日正式加入LIGO兩個探測器的搜索行列,這三個探測器能夠較為精確地給出引力波波源的位置<ref>{{cite web
