Query: Parameterized and inspiral-merger-ringdown consistency tests of gravity
  with multi-band gravitational wave observations   The gravitational wave observations of colliding black holes have opened a
new window into the unexplored extreme gravity sector of physics, where the
gravitational fields are immensely strong, non-linear, and dynamical. 10 binary
black hole merger events observed so far can be used to test Einstein's theory
of general relativity, which has otherwise been proven to agree with
observations from several sources in the weak- or static-field regimes. One
interesting future possibility is to detect gravitational waves from
GW150914-like stellar-mass black hole binaries with both ground-based and
space-based detectors. We here demonstrate the power of testing extreme gravity
with such multi-band gravitational-wave observations. In particular, we
consider two theory-agnostic methods to test gravity using gravitational waves.
The first test is the parameterized test where we introduce generic
non-Einsteinian corrections to the waveform, which can easily be mapped to
parameters in known example theories beyond general relativity. The second test
is the inspiral-merger-ringdown consistency test where one derives the mass and
spin of a merger remnant from the inspiral and merger-ringdown independently
assuming general relativity is correct, and then check their consistency. In
both cases, we use Fisher analyses and compare the results with Bayesian ones
wherever possible. Regarding the first test, we find that multi-band
observations can be crucial in probing certain modified theories of gravity,
including those with gravitational parity violation. Regarding the second test,
we show that future single-band detections can improve upon the current tests
by roughly three orders of magnitude, and further 7-10 times improvement may be
realized with multi-band observations.
