It is likely that for the first time in history we will see a born black hole


In October 2017, astronomers announced the discovery of light and gravitational waves – hundreds of years ago using the theory of general relativity A. Einstein – spatial time bundles – formed from joining two remnants of extremely dense stars, called neutron stars.

The GV170817 crash, named after the first observation on August 17, 2017, marked the beginning of the era of "multi-astrophysics". This term refers to the study of space objects or phenomena using at least two different types of signals.

The data collected by the Laser Interferometer of the Gravitational Wave Observatory (LIGO) showed that the object was formed by a merger about 2.7 times the size of the Sun. This is a recognizable line of neutron stars and black sinks, so the identity of a newly-formed object was unclear: it was the simplest black sink ever discovered, or the largest neutron star.

Initially, astronomers are more likely to interpret JB, but new research suggests that neutron stars, especially supermagnetic neutron stars, are magnetoresistant. LIGO and its related project, Virgo, discover new signals – a 5 seconds crack that began after initial gravitational waves, but before the gamma rays from high energy burst.

The newly detected frequency of the ridge was less than 1 kilohertz (kHz), according to the study. This corresponds to the frequency that the magnet should do and well below the minimum frequency of about 3 black spots of the solar mass – should be at least 2 kHz, said the team members who conducted the test.

"At the very beginning of the gravitational wave of astronomy," said Maurice van Putten, chief researcher at Sejong University in South Korea. "So, it's a good idea to carefully look at the data. We really paid off and we could confirm that the two neutron stars were merged into a larger one."

However, the fate of the magnet remains unknown. Perhaps he will rejoice in the life of a long, fast-rotating neutron star, the so-called. Pulsar, and also can collapse, creating a black sore, writes a study published in September, Monthly Notifications of the Royal Astronomical Society: Letters.
