Gravitational waves recorded from black holes coupled with neutron star fractures

Gravitational waves recorded from black holes coupled with neutron star fractures


For astronomers and astronomers around the world, the arrival of two “signals” opens an unprecedented phase of research: after the discovery of gravitational waves in 2016, and the arrival of many news astronomical instruments with the possibility of using the following phenomena to explore different types of signals, we now reach the heart of new aspects of the universe Search doors are open. One hypothesis is that events such as the connection of black holes and neutron stars can be characterized by a very chaotic and congested environment in parts of the universe.

Identification of two signals

Both signals are called GW200105 and GW200115, which identify the year, month, and day of gravity wave (GW) tracking. The first, discovered on January 5, 2020, was about 900 million years ago when a black hole 8.9 times heavier than the Sun swallowed up a cosmic back-man-like small star, 1.9 times the mass of the Sun The second signal, detected on January 15, 2020, was about a billion years ago and was emitted when a black hole of 5.7 solar masses swallowed a neutron star 1.5 times more mass than the Sun.

New technologies in the game

This record was made possible by the most powerful tools available to researchers: an improved version of the early European Gravity Laboratory (EGO) virgin inventor, located in Cascina (Pisa) in Italy and funded by, worked with and the French National Research Council (CNRS), and Two US advanced Lego detectors (Laser Interferometer Gravity-Wave Laboratory) located in Livingston (Louisiana) and Honford (Washington State); Now kakra (kamiyoka gravitational wave detection) from Japan has been added, and all together they act as a single and gigantic antenna.

Researchers: “We are ready to learn more about the International” “Lego and Virgo continue to reveal catastrophic events that have never been seen before, helping to shed light on a hitherto unexplored cosmic landscape,” said Giovanni Losurdo, Virgin International Coordinator and Infn researcher. “Now we are intentionally updating the inventors – he added – for a deeper understanding of the universe in which we live, we need to look at the universe more and more.”
