A Neutron Star Collision: Gamma Rays & Gravitational Waves

Gravitational waves have been on our radar non-stop lately, from LIGO's fourth reported detection--enhanced by data from Italy's Virgo project--to this year's physics Nobel going to three of LIGO's cofounders. But here we are again and, far from getting old, the news is more exciting than ever: we've picked up a new kind of signal, from merging neutron stars rather than black holes. That's not all, though--while black hole mergers are expected to be difficult or impossible to see, this collision...
