  The X-ray afterglow of short hard bursts (SHBs) of gamma rays provides
compelling evidence that SHBs are produced by highly relativistic jets launched
in the birth of rotationally powered millisecond pulsars in merger of neutron
stars and/or in mass accretion on neutron stars in low mass X-ray binaries.
Gravitational wave detection of relatively nearby neutron star mergers by
Ligo-Virgo, followed by far off-axis short GRBs or orphan afterglows of beamed
away SHBs with an MSP-like light curve will verify beyond doubt the neutron
star merger origin of SHBs.
