GW170817: Observation of Gravitational Waves from a Binary Neutron Star Inspiral.
TLDR
The association of GRB 170817A, detected by Fermi-GBM 1.7 s after the coalescence, corroborates the hypothesis of a neutron star merger and provides the first direct evidence of a link between these mergers and short γ-ray bursts.

GW170104: Observation of a 50-Solar-Mass Binary Black Hole Coalescence at Redshift 0.2.
TLDR
The magnitude of modifications to the gravitational-wave dispersion relation is constrain, the graviton mass is bound to m_{g}≤7.7×10^{-23}  eV/c^{2} and null tests of general relativity are performed, finding that GW170104 is consistent with general relativity.

THE RATE OF BINARY BLACK HOLE MERGERS INFERRED FROM ADVANCED LIGO OBSERVATIONS SURROUNDING GW150914
TLDR
Details of the method and computations are given, including information about the search pipelines, a derivation of the likelihood function for the analysis, a description of the astrophysical search trigger distribution expected from merging BBHs, details on the computational methods, and an analytic method of estimating the detector sensitivity that is calibrated to the measurements.
