The binary neutron star event ligo/virgo gw170817 a hundred and sixty days after merger: Synchrotron emission across the electromagnetic spectrum
Raffaella Margutti,Kate D. Alexander,X. Xie,Lorenzo Sironi,Brian D. Metzger,A. Kathirgamaraju,Wen-fai Fong,P. K. Blanchard,Edo Berger,Andrew MacFadyen,Dimitrios Giannios,C. Guidorzi,A.

TL;DR: In this paper, Chandra, HST and VLA observations of the binary neutron star event GW170817 at <160$ d after merger were reported, and the spectral and temporal evolution of the non-thermal emission from GW 170817 is consistent with both emission from radially stratified quasi-spherical ejecta traveling at mildly relativistic speeds.

Journal ArticleDOI
A Decline in the X-Ray through Radio Emission from GW170817 Continues to Support an Off-axis Structured Jet
Kate D. Alexander,Raffaella Margutti,P. K. Blanchard,Wen-fai Fong,Edo Berger,A. Hajela,Tarraneh Eftekhari,Ryan Chornock,Philip S. Cowperthwaite,Dimitrios Giannios,C. Guidorzi,A. Kathirgamaraju,Andrew MacFadyen,Brian D. Metzger,Matt Nicholl,Lorenzo Sironi,V. A. Villar,Peter K. G. Williams,X. Xie,Jonathan Zrake +19 more
TL;DR: The radio-to-X-ray spectral energy distribution exhibits no evolution into the declining phase as discussed by the authors, which is consistent with the predicted behavior of the successful structured jet expanding into a low-density circumbinary medium, but pure cocoon models with a choked jet cannot be ruled out.
Journal ArticleDOI
Two Years of Nonthermal Emission from the Binary Neutron Star Merger GW170817: Rapid Fading of the Jet Afterglow and First Constraints on the Kilonova Fastest Ejecta

TL;DR: In this article, Chandra and VLA observations of GW170817 at ~521-743 days post merger are presented, and a homogeneous analysis of the entire Chandra data set is performed.
Journal ArticleDOI
Producing magnetar magnetic fields in the merger of binary neutron stars
TL;DR: In this article, the authors present a subgrid model that allows global simulations to take into account the small-scale amplification of the magnetic field which is caused by the development of turbulence during BNS mergers.
