Query: Gravitational-Wave Constraints on an Effective Field-Theory Extension of
  General Relativity   Gravitational-wave observations of coalescing binary systems allow for novel
tests of the strong-field regime of gravity. Using data from the Gravitational
Wave Open Science Center (GWOSC) of the LIGO and Virgo detectors, we place the
first constraints on an effective field-theory based extension of General
Relativity in which only higher-order curvature terms are added to the
Einstein-Hilbert action. We construct gravitational-wave templates describing
the quasi-circular, adiabatic inspiral phase of binary black holes in this
extended theory of gravity. Then, after explaining how to properly take into
account the region of validity of the effective field theory when performing
tests of General Relativity, we perform Bayesian model selection using the two
lowest-mass binary black-hole events reported to date by LIGO and Virgo --
GW151226 and GW170608 -- and constrain this theory with respect to General
Relativity. We find that these data disfavors the appearance of new physics on
distance scales around $\sim 150$ km. Finally, we describe a general strategy
for improving constraints as more observations will become available with
future detectors on the ground and in space.
