For the first time, the researchers have confirmed collision detection between black holes and neutron stars. What is more impressive than confirming a collision like that is that scientists detected two events that occurred only ten separate days in January 2020. The merger sent gravitational waves rustling at 900 million light years to reach the earth.
Scientists say that in every case, neutron stars may be swallowed intact by their black partners. Gravity waves are interference with the curvature of the space-time created by large moving objects. The first time the gravitational wave was measured was five years ago, and scientists who measured waves won the 2017 Nobel Prize in Physics. Since the first measurement, the researchers have been able to identify more than 50 gravitational wave signals made from the merging of pairs of black holes and pairs of neutron stars.
Both black holes and neutron stars are the remnants of the death of large stars, with black holes into the most massive of both. The new study confirmed the detection of gravitational waves in two rare events involving black hole collisions with neutron stars. Gravitational waves are detected by the observatory of national gravity-wave-wave-gravity in the US and by Virgo detectors based in Italy.
There is a third detector which is part of a Japanese-based Ligo-Virgo network called Kagra, but the device is not online during the event. Caltech researcher Ryan Magee said scientists who suspected the system like this existed but could not find until now. The first merger was detected on January 5, 2020, and involved a black hole of about nine times the mass of the sun and solar power neutron stars 1.9.
The second merger was detected on January 15 and involved the six-mass six-mass blackhole and 1.5 solar neutron stars. The signal that shows the merger is strong in just one detector, so the location of the merger in the sky is uncertain. Both Merler occurred outside our galaxy, but scientists had been looking for the Milky Way for decades trying to find neutron stars orbiting black holes.
