On 2019 April 25, the LIGO Livingston detector observed a compact binary coalescence with signal-to-noise ratio 12.9. The Virgo detector was also taking data that did not contribute to detection due to a low signal-to-noise ratio, but were used for subsequent parameter estimation. The 90% credible intervals for the component masses range from to if we restrict the dimensionless component spin magnitudes to be smaller than 0.05). These mass parameters are consistent with the individual binary… Expand
GW190521: A Binary Black Hole Merger with a Total Mass of 150  M_{⊙}.

Distinguishing high-mass binary neutron stars from binary black holes with second- and third-generation gravitational wave observatories

Pulsar J0453+1559: A Double Neutron Star System with a Large Mass Asymmetry

Parameter estimation on gravitational waves from neutron-star binaries with spinning components
Inspiraling binary neutron stars are expected to be one of the most significant sources of gravitational-wave signals for the new generation of advanced ground-based detectors. We investigate howExpand
GW170817: Observation of Gravitational Waves from a Binary Neutron Star Inspiral.
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. Expand
