我们提出了GLADE+，在我们以前的论文中介绍的GLADE星系目录的扩展版本的多信使搜索与先进的引力波探测器。GLADE+结合了来自六个独立但不独立的天文目录的数据：GWGC，2 MPZ，2 MASS XSC，HyperLEDA和WISExSCOSPZ星系目录，以及SDSS-DR 16 Q类星体目录。为了修正CMB标架的特殊运动红移，我们用“Galerkin的贝叶斯原点重建”方法计算了所有B波段星等数据在红移= 0.05以内的星系的特殊速度沿着及其标准差。GLADE+是完整的光度距离Mpc的总预期的B波段光度的星系，并包含了所有最亮的星系提供了90%的总B波段和K波段光度高达dL <$130 Mpc。我们包括恒星质量的估计和个别双星中子星星合并率的星系W1等。这些参数可以帮助在一个给定的引力波本地化体积的星系在他们的主机的可能性方面进行排名，从而可能减少点的数量和总的积分时间需要找到电磁对应。
We present GLADE+, an extended version of the GLADE galaxy catalogue introduced in our previous paper for multimessenger searches with advanced gravitational-wave detectors. GLADE+ combines data from six separate but not independent astronomical catalogues: the GWGC, 2MPZ, 2MASS XSC, HyperLEDA, and WISExSCOSPZ galaxy catalogues, and the SDSS-DR16Q quasar catalogue. To allow corrections of CMB-frame redshifts for peculiar motions, we calculated peculiar velocities along with their standard deviations of all galaxies havingB-band magnitude data within redshiftz= 0.05 using the ‘Bayesian Origin Reconstruction from Galaxies’ formalism. GLADE+ is complete up to luminosity distanceMpc in terms of the total expectedB-band luminosity of galaxies, and contains all of the brightest galaxies giving 90 per cent of the totalB-band andK-band luminosity up todL≃ 130 Mpc. We include estimations of stellar masses and individual binary neutron star merger rates for galaxies withW1 magnitudes. These parameters can help in ranking galaxies in a given gravitational wave localization volume in terms of their likelihood of being hosts, thereby possibly reducing the number of pointings and total integration time needed to find the electromagnetic counterpart.
