Query: Multimessenger Astronomy   Multimessenger astronomy incorporating gravitational radiation is a new and
exciting field that will potentially provide significant results and exciting
challenges in the near future. With advanced interferometric gravitational wave
detectors (LCGT, LIGO, Virgo) we will have the opportunity to investigate
sources of gravitational waves that are also expected to be observable through
other messengers, such as electromagnetic (gamma-rays, x-rays, optical, radio)
and/or neutrino emission. The LIGO-Virgo interferometer network has already
been used for multimessenger searches for gravitational radiation that have
produced insights on cosmic events. The simultaneous observation of
electromagnetic and/or neutrino emission could be important evidence in the
first direct detection of gravitational radiation. Knowledge of event time,
source sky location, and the expected frequency range of the signal enhances
our ability to search for the gravitational radiation signatures with an
amplitude closer to the noise floor of the detector. Presented here is a
summary of the status of LIGO-Virgo multimessenger detection efforts, along
with a discussion of questions that might be resolved using the data from
advanced or third generation gravitational wave detector networks.
