Query: Indications of an unexpected signal associated with the GW170817 binary
  neutron star inspiral   We report experimental evidence at the 2.5$\sigma$ level for an unexpected
signal associated with the GW170817 binary neutron star inspiral. This evidence
derives from a laboratory experiment simultaneously measuring the $\beta$-decay
rates of Si-32 and Cl-36 in a common detector. Whereas the Si-32 and Cl-36
decay rates show no statistical correlation before or after the inspiral, they
are highly correlated ($\sim 95\%$) in the 5 hour time interval immediately
following the inspiral. If we interpret this correlation as arising from the
influence of particles emitted during the inspiral, then we can estimate the
mass $m_{x}$ of these particles from the time delay between the gravity-wave
signal and a peak in the $\beta$-decay data. We find for particles of energy 10
MeV, $m_{x}$ $\lesssim$ 16 eV which includes the neutrino mass region $m_{\nu}$
$\lesssim$ 2 eV. The latter is based on existing limits for the masses $m_{i}$
of the three known neutrino flavors. Additionally, we find that the correlation
is even stronger if we include data in the 80 minute period before the arrival
of the gravity wave signal. Given the large number of radionuclides whose
decays are being monitored at any given time, we conjecture that other groups
may also be in a position to search for statistically suggestive fluctuations
of radionuclide decay rates associated with the GW170817 inspiral, and possibly
with other future inspirals.
