Abstract: We describe the observation of GW170104, a gravitational-wave signal produced by the coalescence of a pair of stellar-mass black holes. The signal was measured on January 4, 2017 at 10∶11:58.6 UTC by the twin advanced detectors of the Laser Interferometer Gravitational-Wave Observatory during their second observing run, with a network signal-to-noise ratio of 13 and a false alarm rate less than 1 in 70 000 years. −0.07 . We constrain the magnitude of modifications to the gravitational-wave dispersion relation … Show more

“…The BBH waveform models have been further improved over the years and many applications to detection have already followed. In the context of testing the dynamical sector of general relativity (GR) [45], for instance, GW150914, GW151226 and GW170104 showed no statistical significant evidence on deviations from PN coefficients of the GW phase predicted by GR [5,6,45]. In [46], GW150914 was directly compared with NR simulations and it was shown that they are mutually consistent.…”

“…Observations of black holes are undergoing a revolution, with the advent of gravitational wave astronomy [2][3][4][5] and the promise of very-longbaseline radio observations of supermassive black holes by the Event Horizon Telescope [6,7]. While black holes are consistent with all electromagnetic and gravitational wave observations to date [4,5,[8][9][10], no experiment has been able probe spacetime near the event horizon [11][12][13]. Moreover, the event horizon is at the heart of the BH information paradox [14], and the role of black holes in a quantum theory of gravity is an open question.…”

“…Recently, the LIGO Scientific Collaboration and Virgo Collaboration, based on data acquired by the Advanced LIGO [2] and Advanced Virgo [3] detectors, have announced detections of gravitational waves from coalescing stellar mass black hole binaries [4][5][6][7][8][9] and a neutron star binary [10]. This opened up the era of gravitational wave astronomy.…”
