- Аннотация: On August 14, 2017 at 10∶30:43 UTC, the Advanced Virgo detector and the two Advanced LIGO detectors coherently observed a transient gravitational-wave signal produced by the coalescence of two stellar mass black holes, with a false-alarm rate of ≲ 1 in 27 000 years. The signal was observed with a three-detector network matched-filter signal-to-noise ratio of 18. The inferred masses of the initial black holes are 30. 5 + 5.7 − 3.0 M ⊙ and 25 . 3 + 2.8 − 4.2 M ⊙ (at the 90% credible level). The luminosity distance of the source is 54 0 + 130 − 210 Mpc , corresponding to a redshift of z = 0.1 1 + 0.03 − 0.04 . A network of three detectors improves the sky localization of the source, reducing the area of the 90% credible region from 1160 deg 2 using only the two LIGO detectors to 60 deg 2 using all three detectors. For the first time, we can test the nature of gravitational-wave polarizations from the antenna response of the LIGO-Virgo network, thus enabling a new class of phenomenological tests of gravity.
