It sort of makes sense this might involve magnetars. If a neutron star with
a huge magnetic field, ~ 10^{10}T, collides with another neutron star or
black hole the sudden reconfiguration of the magnetic field might send a
huge electromagnetic pulse. Of course hypothetical statements could at this
time easily be wrong.
