Query: A search for intermediate-mass black holes mergers in the second
  LIGO--Virgo observing run with the Bayes Coherence Ratio   The detection of an intermediate-mass black hole population ($10^2-10^6\
M_\odot$) will provide clues to their formation environments (e.g., disks of
active galactic nuclei, globular clusters) and illuminate a potential pathway
to produce supermassive black holes. Ground-based gravitational-wave detectors
are sensitive to a subset of such mergers and have been used to detect one
$142^{+28}_{-16}\ M_\odot$ intermediate-mass black hole formation event.
However, ground-based detector data contain numerous incoherent short duration
noise transients that can mimic the gravitational-wave signals from merging
intermediate-mass black holes, limiting the sensitivity of searches. Here we
search for binary black hole mergers using a Bayesian-inspired ranking
statistic which measures the coherence or incoherence of triggers in
multiple-detector data. We use this statistic to identify candidate events with
lab-frame total masses $\gtrsim55\ M_\odot$ using data from LIGO's second
observing run. Our analysis does not yield evidence for new intermediate-mass
black holes. However, we find support for some stellar-mass binary black holes
not reported in the first LIGO--Virgo gravitational-wave transient catalog,
GWTC-1.
