The neutron stars — each fitting roughly the mass of the Sun into a city-sized space — have a combined mass greater than any other pair of neutron stars ever observed. “From conventional observations with light, we already knew of 17 binary neutron star systems in our own galaxy and we have estimated the masses of these stars,” said Ben Farr, a LIGO team member from the University of This is a time-frequency representation (spectrogram) of the LIGO detectors data which combines both the LIGO-Hanford and LIGO-Livingston data coherently for 2017-10-16 · On 2017 August 17, the gravitational-wave event GW170817 was observed by the Advanced LIGO and Virgo detectors, and the gamma-ray burst (GRB) GRB 170817A was observed independently by the Fermi Gamma-ray Burst Monitor, and the Anticoincidence Shield for the Spectrometer for the International Gamma-Ray Astrophysics Laboratory.

Neutron Star Merger. This visualization shows the coalescence of two orbiting neutron stars. The left panel contains a visualization of the matter of the neutron stars. The different colored layers are different densities,which have been made transparent to show more structure. The right panel shows how space-time is distorted near the collisions. The spiral wave distortions at the end of the merger propagate to Earth and are measured as gravitational waves.

“When we were first planning LIGO back in the late 1980s, we knew that we would ultimately need an international network of gravitational-wave observatories, including Europe, to help localize the gravitational-wave sources so that light-based telescopes can follow up and study the glow of events like this neutron star merger,” says Caltech’s Fred Raab, LIGO associate director for observatory operations.

The August 2017 neutron star merger was witnessed by both LIGO detectors, one in Livingston, Louisiana, and one in Hanford, Washington, together with a host of light-based telescopes around the world (neutron star collisions produce light, while black hole collisions are generally thought not to do so).

As of 2020, LIGO has made 47 detections of gravitational radiation. mergers of a black hole binary, two were the merger of a neutron star

Neutron Star Merger.

Multi-messenger Observations of a Binary Neutron Star Merger - IOPscience 2017-02-22 · However, we cannot yet exclude the possibility that model M2 is consistent for lower-mass stars (neutron star progenitors), since our predicted cosmic NS–NS merger rate density for this model is ~250 Gpc −3 yr −1 and is currently below the upper limits expected by Advanced LIGO (see Section 6). Now LIGO and its sister experiment, Virgo, have broken ground yet again with their joint detection of gravitational waves from the merger of two neutron stars (see Video 1). Unlike a black hole merger, which is practically invisible, a neutron star merger event (Fig. 1 ) is accompanied by emission across the electromagnetic spectrum. After LIGO's first identification of a neutron star merger, a burst of gamma-ray light told scientists that the merger occurred in an old galaxy around 130 million light-years from Earth.
