Inferring the post-merger gravitational wave emission from binary neutron star coalescences
Katerina Chatziioannou, James Alexander Clark, Andreas Bauswein +3
We present a robust method to characterize the gravitational wave emission from the remnant of a neutron star coalescence. Our approach makes only minimal assumptions about the mor…
On the Progenitor of Binary Neutron Star Merger GW170817
The LIGO Scientific Collaboration, the Virgo Collaboration, B. P. Abbott +1095
On 2017 August 17 the merger of two compact objects with masses consistent with two neutron stars was discovered through gravitational-wave (GW170817), gamma-ray (GRB 170817A), and…
Extended gamma-ray sources around pulsars constrain the origin of the positron flux at Earth
A. U. Abeysekara, A. Albert, R. Alfaro +113
The unexpectedly high flux of cosmic ray positrons detected at Earth may originate from nearby astrophysical sources, dark matter, or unknown processes of cosmic-ray secondary prod…
GW170608: Observation of a 19-solar-mass Binary Black Hole Coalescence
The LIGO Scientific Collaboration, the Virgo Collaboration, B. P. Abbott +1101
On June 8, 2017 at 02:01:16.49 UTC, a gravitational-wave signal from the merger of two stellar-mass black holes was observed by the two Advanced LIGO detectors with a network signa…
Gravitational Waves and Gamma-rays from a Binary Neutron Star Merger: GW170817 and GRB 170817A
LIGO Scientific Collaboration, Virgo Collaboration, Fermi Gamma-Ray Burst Monitor +1
On 2017 August 17, the gravitational-wave event GW170817 was observed by the Advanced LIGO and Virgo detectors, and the gamma-ray burst (GRB) GRB 170817A was observed independently…
Search for post-merger gravitational waves from the remnant of the binary neutron star merger GW170817
The LIGO Scientific Collaboration, the Virgo Collaboration, B. P. Abbott +1105
The first observation of a binary neutron star coalescence by the Advanced LIGO and Advanced Virgo gravitational-wave detectors offers an unprecedented opportunity to study matter…
