Glowing wreckage and gravity waves as neutron stars collide

While two merging black holes are thought to produce nothing detectable beyond a crescendo of gravitational waves, events involving two neutron stars or a neutron star and a black hole could also leave behind a glowing wreckage for telescopes to see.

There has been speculation on Twitter, in a New Scientist article and on astronomer Peter Coles’s blog that such a link has been found, based on publicly available observation logs.

“If the detection is true, it would be transformative for the field and probably one of the greatest discoveries in astronomy,” said Enrico Ramirez-Ruiz of the University of California, Santa Cruz, who refused to discuss any specific results.
