摘要:

利用引力波定位恒星质量的双星黑洞合并,对于理解双星宿主星系的性质,观察合并可能产生的电磁辐射,或将其用作宇宙学距离阶梯至关重要。这种定位的精度可以大大增加与先前的天体物理信息的二元系统。特别是,限制双星的倾角可以减少源的距离不确定性。在这里,我们提出了第一套现实的本地化的二进制黑洞合并,包括不同的事先约束的二进制的倾向。我们发现,先验信息的倾斜可以减少本地化体积的一个因素3。我们讨论了两个天体物理方案的利益:(i)后续搜索波束电磁/中微子同行和(ii)合并活动星系核的吸积盘。

英文摘要:

The localization of stellar-mass binary black hole mergers using gravitational waves is critical in understanding the properties of the binaries' host galaxies, observing possible electromagnetic emission from the mergers, or using them as a cosmological distance ladder. The precision of this localization can be substantially increased with prior astrophysical information about the binary system. In particular, constraining the inclination of the binary can reduce the distance uncertainty of the source. Here we present the first realistic set of localizations for binary black hole mergers, including different prior constraints on the binaries' inclinations. We find that prior information on the inclination can reduce the localization volume by a factor of 3. We discuss two astrophysical scenarios of interest: (i) follow-up searches for beamed electromagnetic/neutrino counterparts and (ii) mergers in the accretion disks of active galactic nuclei.
