摘要：

LISA will be able to detect gravitational waves from inspiralling massive black-hole (MBH) binaries out to redshifts z > 10. If the binary masses and luminosity distances can be extracted from the LISA data stream, this information can be used to reveal the merger history of MBH binaries and their host galaxies in the evolving universe. Since this parameter extraction generally requires that LISA observe the inspiral for a significant fraction of its yearly orbit, carrying out this programme requires adequate sensitivity at low frequencies, f < 10(-4) Hz. Using several candidate low-frequency sensitivities, we examine LISA's potential for characterizing M13H binary coalescences at redshifts z > 1. The results underscore the need for more detailed work towards understanding the potential scientific value of the lowfrequency part of LISA's sensitivity band.
