论文摘要
巨大的黑洞二进制文件（质量$ 10^4-10^7 m _ {\ odot} $）的合并导致引力波排放，可与即将到来的Lisa天文台检测到高红移（$ Z \ sim 20 $）。我们将各种红移的理论上衍生的合并率与凭经验动机的处方相结合，该处方连接了暗物质光环及其中央黑洞的质量。使用对二进制黑洞（CHIRP或减少）质量的预期限制，它们的质量比和红移不确定性，我们预测了对三种不同的置信度的五年lisa lissa调查，对占用分数的测量精度，黑洞质量质量的统一分数，归一化和斜率 - 光晕质量 - 光晕质量的质量。我们使用丽莎定位椭圆的预期尺寸，以估计电磁对应物的数量到引力源，这些源可通过未来的宽场光学调查（例如LSST）检测到。
The coalescence of massive black hole binaries (with masses $10^4 - 10^7 M_{\odot}$) leads to gravitational wave emission that is detectable out to high redshifts ($z \sim 20$) with the forthcoming LISA observatory. We combine the theoretically derived merger rates for dark matter haloes at various redshifts, with an empirically motivated prescription that connects the mass of a dark matter halo and that of its central black hole. Using the expected constraints on the (chirp or reduced) masses of binary black holes, their mass ratios and redshift uncertainties, we forecast the measurement precision on the occupation fraction, normalization and slope of the black hole mass - halo mass relation at various redshifts, assuming a five-year LISA survey for three different confidence scenarios. We use the expected sizes of the LISA localization ellipses on the sky to estimate the number of electromagnetic counterparts to the gravitational wave sources which are detectable by future wide-field optical surveys, such as LSST.
