Scientists identify gravitational waves as the 4 new black holes collide



Astronomers now rely on their fingers to lift gravity waves.

Scientists with LIGO and Virgo gravitational wave observatories offer four new sets of brightness in the space. These additions bring the total number up to 11, and researchers have pointed out that, in a study published on December 3, in arXiv.org, the great achievements of the first gravity waves in 2015SN: 3/5/16, p. 6).

One of the 11 sets of waves was triggered by a strong collision of two black holes. One of the remaining discoveries reported in October 2017 emerged from the shock of the two star bodies called neutron stars (SN: 11/11/17, p. 6).

The contest begins to detect how often the space is exposed and the properties of shady cosmic figures that open the spark. For example, in the history of the universe, data suggest that the black hole can be consolidated earlier, according to researchers on December 3 in the second study published on arXiv.org. Also, in the team's opinion, several combinations include black holes of about 50 times the size of the sun.

"They have clear evidence [larger] there is no black hole, "said Daniel Holtz, an astrophysicist at the University of Chicago, LIGO. Some theoretical physicists have predicted the horrors of large volumes of black holes, based on the physics of the star blasts that release the cosmic valleys.

Flat holes release one of the new black clamps. The combined mass of collisions was the largest, and one black hole is about 50 times the size of the sun, and the second is 34 times the mass of the sun. These flashlights are farther away from the previous definition: about 9 billion light years out of the Earth, or several billions. According to Emanuele Berti, a physicist at the Johns Hopkins University, this is not about research. "It's very funny."

Two detectors of LIGO – Hanford, Washington and Livingston, La, and Vijjo, located in Pisa near Italy, are for upgrades to the next spring. Equipment modernization can triple the number of gravity waves, says Holzz. "We will concentrate on more."
