The Geometry, Energetics, and Environment of the Binary Neutron Star<br>
Merger GW170817: The Radio View<br>
<br>
I will discuss the major uncertainties regarding the geometry,<br>
energetics, and environment of the first EM/GW binary neutron star<br>
merger GW170817. In particular I will look at the origin of the radio<br>
emission, how it differs from the early-time optical/infrared<br>
emission, and what that tells us about how the explosion proceeded. I<br>
will show how constraints from the radio lightcurve, polarization, and<br>
Very Long Baseline Interferometry helped provide evidence for a broad,<br>
mildly relativistic "cocoon" along with a narrow jet. This <br>
broke degeneracies in the gravitational wave data analysis to provide<br>
inclination constraints and improved measurements of the Hubble<br>
Constant.<br>
