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 produced electromagnetic waves across a broad portion of the spectrum, allowing multiple telescopes to...
