We have just published evidence in Nature Astronomy for what might be producing mysterious bursts of radio waves coming from distant galaxies, known as fast radio bursts or FRBs.
Two colliding neutron stars – each the super-dense core of an exploded star – produced a burst of gravitational waves when they merged into a “supramassive” neutron star. We found that two and a half hours later they produced an FRB when the neutron star collapsed into a black hole.
