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…
An Intercomparison Study of Two Proximate Damped Ly Systems with Residual Flux upon the Ly Absorption Trough toward Quasars
Xiaoyi Xie, Hongyan Zhou, Xiang Pan +6
In this paper, we present an intercomparison study of two quasars, SDSS J145618.32+340037.2 and SDSS J215331.50-025514.1, which have proximate damped Lya systems (PDLAs) with resid…
Numerical simulations of the jet dynamics and synchrotron radiation of binary neutron star merger event GW170817/GRB170817A
Xiaoyi Xie, Jonathan Zrake, Andrew MacFadyen
We present numerical simulations of energetic flows propagating through the debris cloud of a binary neutron star (BNS) merger. Starting from the scale of the central engine, we us…
The Binary Neutron Star event LIGO/VIRGO GW170817 a hundred and sixty days after merger: synchrotron emission across the electromagnetic spectrum
Raffaella Margutti, K. D. Alexander, X. Xie +17
We report deep Chandra, HST and VLA observations of the binary neutron star event GW170817 at d after merger. These observations show that GW170817 has been steadily bright…
