    A neutron star merger produces a black hole, but also a significant amount of ejected matter. We know that a lot of stuff must be shot out because astronomers can see radiation from this material, which is observed as a kilonova.

      Merging neutron stars: The unfolding story of a kilonova told in X-rays | Penn State University
      Astronomers may have detected a kilonova — a powerful event that results when two neutron stars merge — in an event called GW170817. Several years after its first detection, the event has continued to emit X-rays that were detected with NASA’s Chandra X-ray Observatory and analyzed by an international team including Penn State scientists.
