Sentences with phrase «as a neutron star merger»

A long - standing goal of the LIGO project has been the development of multi-messenger astronomy — the near - simultaneous observation of cataclysmic events such as neutron star mergers or supernova explosions in both gravitational waves and light, providing details about the astrophysics of these phenomena that can't be revealed through either alone.

«Previously, as anticipated, gamma ray detectors had observed bursts of gamma rays such as were expected from neutron star mergers.

«Our theories predicted that neutron star binaries, which would inevitably merge as they emit gravitational waves, would produce a short and distinctive burst of gamma rays at the moment of their merger,» Mészáros said.

All the previous gravitational - wave detections since the first in September 2015 had been the result of two merging black holes — objects much more massive than a neutron star — which have left only gravitational waves as fleeting clues of their merger.

Researchers define sensitivity as the distance to which a detector could spot the merger of two neutron stars with masses 1.4 times the sun's.

The most important discovery in astronomy in 2017 was the groundbreaking discovery of a gravitational wave event GW170817 due to the merger of two neutron stars as well as its associated short GRB (gamma ray burst) 170817A and other electromagnetic counterpart emissions in multi-wavelength.

It was as if the neutron star merger, sometimes referred to as a kilonova, had somehow forgotten about them.

A few hours after the initial detection by LIGO and Virgo, the source of the neutron star merger had been localized to an area roughly the size of 150 full moons, or about the size of your palm if you stick it as far away from your eyes as possible.

So far, only the gravitational waves from black hole mergers have been detected, but as the sensitivity of laser interferometers increases, scientists hope to detect collisions between neutron stars, for example.

Within the next 24 hours, as the night sky swept west, observatories In Hawaii, Australia and South Africa would each make their own observations, piecing together a movie of the first neutron star merger ever observed.

This is the first time that scientists have measured both the gravitational waves and electromagnetic waves from a single cosmic event, connecting a GRB with a neutron star merger and opening a brand - new way to study the universe — known as «multi-messenger astronomy.»

Last year astronomers around the world witnessed the merger of two neutron stars as gravitational waves, light, radio and gamma rays, but the aftermath of the mashup hasn't played out quite as expected.

Subsequently, matter from the debris of the merger that swirls rapidly around the newly created new black hole has been modelled as amplifying the strength of the combined magnetic field left over by the neutron stars after their merger over the next 11 milliseconds.
