Query: Hunting for Dark Particles with Gravitational Waves   The LIGO observation of gravitational waves from a binary black hole merger
has begun a new era in fundamental physics. If new dark sector particles, be
they bosons or fermions, can coalesce into exotic compact objects (ECOs) of
astronomical size, then the first evidence for such objects, and their
underlying microphysical description, may arise in gravitational wave
observations. In this work we study how the macroscopic properties of ECOs are
related to their microscopic properties, such as dark particle mass and
couplings. We then demonstrate the smoking gun exotic signatures that would
provide observational evidence for ECOs, and hence new particles, in
terrestrial gravitational wave observatories. Finally, we discuss how
gravitational waves can test a core concept in general relativity: Hawking's
area theorem.
