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...
LIGO再获双中子星碰撞产生的引力波
LIGO 双中子星 碰撞 引力波
2020/1/15
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》。
NSF statement on latest LIGO-Virgo detection of binary black hole merger（图）
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。
LIGO and Virgo make first detection of gravitational waves produced by colliding neutron stars（图）
LIGO Virgo first detection gravitational waves produced colliding neutron stars
2017/10/26
For the first time, scientists have directly detected gravitational waves -- ripples in space-time -- in addition to light from the spectacular collision of two neutron stars. This marks the first tim...

LIGO And Virgo Observatories Jointly Detect Black Hole Collision
2017/10/24
In August, detectors on two continents recorded gravitational wave signals from a pair of black holes colliding. This discovery, announced today, is the first observation of gravitational waves by thr...
