The observation of a gravitational wave （GW） emitted from the merger of binary black holes [1] won a well-deserved Nobel Prize this year for the leaders of the Laser Interferometry Gravita- tional-Wave Observatory （LIGO）, and raised hopes that future gravitational wave detections involving matter and not just vacuum （black hole） solutions of the Einstein field equations might be made in coincidence with other electromagnetic or neutrino signals. Although viewed as difficult and probably requiring substantial longer-term improvement of technology, such multimessenger astronomy was deemed a ＂holy grail＂ having potentially momen- tous implications.
