Query: Neutron Star Extreme Matter Observatory: A kilohertz-band
  gravitational-wave detector in the global network   Gravitational waves from coalescing neutron stars encode information about
nuclear matter at extreme densities, inaccessible by laboratory experiments.
The late inspiral is influenced by the presence of tides, which depend on the
neutron star equation of state. Neutron star mergers are expected to often
produce rapidly-rotating remnant neutron stars that emit gravitational waves.
These will provide clues to the extremely hot post-merger environment. This
signature of nuclear matter in gravitational waves contains most information in
the 2-4 kHz frequency band, which is outside of the most sensitive band of
current detectors. We present the design concept and science case for a neutron
star extreme matter observatory (NEMO): a gravitational-wave interferometer
optimized to study nuclear physics with merging neutron stars. The concept uses
high circulating laser power, quantum squeezing and a detector topology
specifically designed to achieve the high-frequency sensitivity necessary to
probe nuclear matter using gravitational waves. Above one kHz, the proposed
strain sensitivity is comparable to full third-generation detectors at a
fraction of the cost. Such sensitivity changes expected event rates for
detection of post-merger remnants from approximately one per few decades with
two A+ detectors to a few per year, and potentially allows for the first
gravitational-wave observations of supernovae, isolated neutron stars, and
other exotica.
