Properties of the Binary Black Hole Merger GW150914
Abstract: On September 14, 2015, the Laser Interferometer Gravitational-Wave Observatory (LIGO) detected a gravitational-wave transient (GW150914); we characterize the properties of the source and its parameters. The data around the time of the event were analyzed coherently across the LIGO network using a suite of accurate waveform models that describe gravitational waves from a compact binary system in general relativity. GW150914 was produced by a nearly equal mass binary black hole of masses 36 þ5 −4 M ⊙ and 29 þ4 −…

“…We find this analysis to be broadly consistent with the results in Ref. [2]. By using the difference between two precessing waveform models as a proxy for systematic errors due to waveform uncertainty, we can compute a more accurate systematic error than what was possible in Ref.…”

“…9 and 13. The SEOB/IMRPP values stated here are directly comparable to Table I of [37] for GW150914 and to Table I of [4] for GW170104, and are broadly consistent with published LIGO analyses.…”

“…Figure 20 shows the posterior densities for the M − q and q − χ eff subspaces. The consistency between the three waveform models is in agreement with previous studies, demonstrating that systematic errors were below the statistical errors for this event [6,8,123].…”
