Instabilities in neutron-star postmerger remnants
Xiaoyi Xie, Ian Hawke, Andrea Passamonti +1
Using nonlinear, fully relativistic, simulations we investigate the dynamics and gravitational-wave signature associated with instabilities in neutron star postmerger remnants. For…
Two years of non-thermal emission from the binary neutron star merger GW170817: rapid fading of the jet afterglow and first constraints on the kilonova fastest ejecta
A. Hajela, R. Margutti, K. D. Alexander +27
We present Chandra and VLA observations of GW170817 at ~521-743 days post merger, and a homogeneous analysis of the entire Chandra data set. We find that the late-time non-thermal…
Off-axis synchrotron light curves from full-time-domain moving-mesh simulations of jets from massive stars
Xiaoyi Xie, Andrew MacFadyen
We present full-time-domain, moving-mesh, relativistic hydrodynamic simulations of jets launched from the center of a massive progenitor star and compute the resulting synchrotron…
A Strange EUV Emission: Scattered Continuum in the Lymann Limit Absorption Edge toward the Quasar SDSS J125903.26+621211.5?
Xiang Pan, Shaohua Zhang, Hongyan Zhou +5
We identified a peculiar proximate sub-damped Lya absorption system (sub-DLA) at z=3.234 with a neutral hydrogen column density of toward the…
Radio sky maps of the GRB 170817A afterglow from simulations
Jonathan Zrake, Xiaoyi Xie, Andrew MacFadyen
We present synthetic radio images of the GRB170817A afterglow, computed from moving-mesh hydrodynamic simulations of binary neutron star merger outflows. Having expanded for nearly…
A Decline in the X-ray through Radio Emission from GW170817 Continues to Support an Off-Axis Structured Jet
K. D. Alexander, R. Margutti, P. K. Blanchard +17
We present new observations of the binary neutron star merger GW170817 at days post-merger, at radio (Karl G. Jansky Very Large Array; VLA), X-ray (Chandra X-ra…
