Scientists, including from The Australian National University (ANU), say they have detected a black hole swallowing a neutron star for the first time. ...
On Wednesday 14 August 2019, gravitational-wave discovery machines in the United States and Italy detected ripples in space and time from the cataclysmic event that happened about 8,550 million trillion kilometres away from Earth.
Professor Susan Scott, from the ANU Research School of Physics, said the achievement completed the team’s trifecta of observations on their original wish list, which included the merger of two black holes and the collision of two neutron stars.
“About 900 million years ago, this black hole ate a very dense star, known as a neutron star, like Pac-man – possibly snuffing out the star instantly,” said Professor Scott ... “The ANU SkyMapper Telescope responded to the detection alert and scanned the entire likely region of space where the event occurred, but we’ve not found any visual confirmation.”
Scientists are still analysing the data to confirm the exact size of the two objects, but initial findings indicate the very strong likelihood of a black hole enveloping a neutron star. The final results are expected to be published in scientific journals. ...
