Query: A Triple Origin for the Heavy and Low-Spin Binary Black Holes Detected
  by LIGO/Virgo   We explore the masses, merger rates, eccentricities, and spins for field
binary black holes driven to merger by a third companion through the
Lidov-Kozai mechanism. Using a population synthesis approach, we model the
creation of stellar-mass black hole triples across a range of different initial
conditions and stellar metallicities. We find that the production of
triple-mediated mergers is enhanced at low metallicities by a factor of ~100
due to the lower black hole natal kicks and reduced stellar mass loss. These
triples naturally yield heavy binary black holes with near-zero effective
spins, consistent with most of the mergers observed to date. This process
produces a merger rate of between 2 and 25 Gpc^-3 yr^-1 in the local universe,
suggesting that the Lidov-Kozai mechanism can potentially explain all of the
low-spin, heavy black hole mergers observed by Advanced LIGO/Virgo. Finally, we
show that triples admit a unique eccentricity and spin distribution that will
allow this model to be tested in the near future.
