The Combined Ultraviolet, Optical, and Near-Infrared Light Curves of the Kilonova Associated with the Binary Neutron Star Merger GW170817: Unified Data Set, Analytic Models, and Physical Implications
V. Ashley Villar, James Guillochon, Edo Berger +10
We present the first effort to aggregate, homogenize, and uniformly model the combined ultraviolet, optical, and near-infrared dataset for the electromagnetic counterpart of the bi…
Improved constraints on H0 from a combined analysis of gravitational-wave and electromagnetic emission from GW170817
C. Guidorzi, R. Margutti, D. Brout +17
The luminosity distance measurement of GW170817 derived from GW analysis in Abbott et al. 2017 (here, A17:H0) is highly correlated with the measured inclination of the NS-NS system…
