摘要:We explore a potential LISA-Taiji network to fast and accurately localize the coalescing massive black hole binaries. For an equal-mass binary located at redshift of 1 with a total intrinsic mass of 10 5 M ⊙ , the LISA-Taiji network may achieve almost four orders ofmagnitude improvement on the source localization region compared to an individual detector. The precision measurement of skylocation from the gravitational-wave signal may completely identify the host galaxy with low redshifts prior to the final black holemerger. Such identification of the host galaxy is vital for the follow-up variability in electromagnetic emissions of the circumbinarydisc when the binary merges to a new black hole and enables the coalescing massive black hole binaries to be used as a standardsiren to probe the expansion history of the Universe.
