Query: The last three years: multiband gravitational-wave observations of
  stellar-mass binary black holes   Understanding the formation and evolution of the stellar-mass binary black
holes discovered by LIGO and Virgo is a challenge that spans many areas of
astrophysics, from stellar evolution, dynamics and accretion disks, to possible
exotic early universe processes. Over the final years of their lives,
stellar-mass binaries radiate gravitational waves that are first observable by
space-based detectors (such as LISA) and then ground-based instruments (such as
LIGO, Virgo and the next generation observatories Cosmic Explorer and the
Einstein Telescope). Using state-of-the-art waveform models and
parameter-estimation pipelines for both ground- and space-based observations,
we show that (the expected handful of) these multiband observations will allow
at least percent-level measurements of all 17 parameters that describe the
binary, the possible identification of a likely host galaxy, and the
forewarning of the merger days in advance allowing telescopes at multiple
wavelengths to search for any electromagnetic signature associated to it.
Multiband sources will therefore be a gold mine for astrophysics, but we also
show that they could be less useful as laboratories for fundamental tests of
general relativity than has been previously suggested.
