TL;DR: In this paper, the authors presented a search for GWs from the remnant of the binary neutron star merger GW170817 using data from Advanced LIGO and Advanced Virgo.

TL;DR: In this paper, the authors search for high-energy neutrinos from the binary neutron star merger in the GeV-EeV energy range using the Antares, IceCube, and Pierre Auger Observatories.

TL;DR: In this paper, the authors presented a search for gravitational waves from the remnant of the binary neutron star merger GW170817 using data from Advanced LIGO and Advanced Virgo and found no signal from the post-merger remnant.

TL;DR: In this paper, a set of models of metal-poor (Z ⊙/10) single helium stars with pre-pulse masses >50 M were computed using the MESA software instrument, and it was shown that after a pulse, heat deposited throughout the layers of the star that remain bound causes it to expand to more than 100 R for periods of 102-104 yr depending on the mass of the progenitor.

TL;DR: It is shown that solely with chirp mass measurements, it is possible to constrain natal kick prescriptions and the relative fraction of systems originating from each formation channel with $\mathcal{O}(100)$ of confident detections.
