Query: Future prospects for ground-based gravitational wave detectors $-$ The
  Galactic double neutron star merger rate revisited   We present the Galactic merger rate for double neutron star (DNS) binaries
using the observed sample of eight DNS systems merging within a Hubble time.
This sample includes the recently discovered, highly relativistic DNS systems
J1757$-$1854 and J1946+2052, and is approximately three times the sample size
used in previous estimates of the Galactic merger rate by Kim et al. Using this
sample, we calculate the vertical scale height for DNS systems in the Galaxy to
be $z_0 = 0.4 \pm 0.1$ kpc. We calculate a Galactic DNS merger rate of
$\mathcal{R}_{\rm MW} = 42^{+30}_{-14}$ Myr$^{-1}$ at the 90% confidence level.
The corresponding DNS merger detection rate for Advanced LIGO is
$\mathcal{R}_{\rm LIGO} = 0.18^{+0.13}_{-0.06} \times \left( D_{\rm r}/100 \
\rm Mpc \right)^3 \rm yr^{-1}$, where $D_{\rm r}$ is the range distance. Using
this merger detection rate and the predicted range distance of 120$-$170 Mpc
for the third observing run of LIGO (Laser Interferometer Gravitational-wave
Observatory, Abbott et al.), we predict, accounting for 90% confidence
intervals, that LIGO$-$Virgo will detect anywhere between zero and two DNS
mergers. We explore the effects of the underlying pulsar population properties
on the merger rate and compare our merger detection rate with those estimated
using different formation and evolutionary scenario of DNS systems. As we
demonstrate, reconciling the rates is sensitive to assumptions about the DNS
population, including its radio pulsar luminosity function. Future constraints
from further gravitational wave DNS detections and pulsar surveys anticipated
in the near future should permit tighter constraints on these assumptions.
