A 'bang' in LIGO and Virgo detectors signals most massive gravitational wave source yet（图）
bang LIGO Virgo detectors signals massive gravitational source yet
2020/9/4
For all its vast emptiness, the universe is humming with activity in the form of gravitational waves. Produced by extreme astrophysical phenomena, these reverberations ripple forth and shake the fabri...
LIGO-Virgo finds mystery object in gap between neutron stars and black holes（图）
LIGO-Virgo mystery object gap between neutro holes
2020/7/3
When the most massive stars die, they collapse under their own gravity and leave behind black holes. When stars that are a bit less massive die, they explode in supernovas and leave behind dense, dead...

日前，美国激光干涉引力波天文台（LIGO）科学合作组织和欧洲处女座（Virgo）引力波探测器合作组织共同宣布，第二次探测到双中子星并合产生的引力波事件，编号为GW190425。相关研究结果已提交给《天体物理学杂志》。
On April 25, NSF's Laser Interferometer Gravitational-Wave Observatory (LIGO) and the European-based Virgo detector registered gravitational waves from what appears to be a crash between two neutron s...
美国激光干涉引力波天文台（LIGO）有关负责人3月19日表示，该机构计划于4月初启动第三轮为期一年的科学探测，有关设备在维护和升级后灵敏度提高，有望发现更多引力波事件。
LIGO的主要设备是位于美国路易斯安那州利文斯顿和华盛顿州汉福德的两个探测仪。利文斯顿天文台负责人约瑟夫·贾伊姆3月19日表示，这两个探测仪将于4月1日左右恢复运行。2017年8月25日，LIGO暂停运行，进行新一轮调试升级。

NSF latest LIGO-Virgo binary black hole merger
2017/12/19
Scientists supported by the National Science Foundation (NSF) recently announced the detection of the merger of two relatively "light" black holes, 7 and 12 times the mass of the sun, respectively, at...
两个黑洞（中子星）在强大引力的相互作用下相互绕转着靠近彼此，越转越快，直至最后发生碰撞并合。在不断靠近彼此的过程中，就已经产生了引力波。理论预言，如果它们质量相当，在相互靠近的过程中，引力波的辐射不仅带走了能量，还能使得轨道从一个大椭圆较快地逐渐收缩到一个圆，到最后发出被LIGO探测到的高频强引力波信号时，轨道已经很圆了。
