Observations of gravitational waves from binary black hole (BBH) mergers have measured the redshift evolution of the BBH merger rate. The number density of galaxies in the Universe evolves differently with redshift based on their physical properties, such as their stellar masses and star formation rates. In this work we show that the measured population-level redshift distribution of BBHs sheds light on the properties of their probable host-galaxies. We first assume that the hosts of BBHs can be described by a mixture model of galaxies weighted by stellar mass or star formation rate, and find that we can place upper limits on the fraction of mergers coming from a stellar mass weighted sample of galaxies. We then constrain parameters of a physically motivated power-law delay-time distribution using GWTC-3 data, and self-consistently track galaxies in the \textsc{UniverseMachine} simulations with this delay-time model to infer the probable host-galaxies of BBHs over a range of redshifts. We find that the inferred host-galaxy distribution at redshift $z=0.21$ has a median star formation rate $\sim 0.9\,M_\odot\mathrm{yr}^{-1}$ and a median stellar mass of $\sim 1.9 \times 10^{10}\,M_\odot$. We also provide distributions for the mean stellar age, halo mass, halo radius, peculiar velocity, and large scale bias associated with the host-galaxies, as well as their absolute magnitudes in the B- and ${ \rm K_s}$-bands. Our results can be used to design optimal electromagnetic follow-up strategies for BBHs, and also to aid the measurement of cosmological parameters using the statistical dark siren method.

两个致密物体的合并,比如两颗中子星或一颗中子星和一个黑洞,很可能是短伽马射线暴的起源。这些事件也是有希望的引力波来源,目前正在激发国际引力波探测器网络的相关搜索。在这里,我们描述了一个搜索的引力波从螺旋阶段的两个合并紧凑的对象,在巧合的短伽玛射线暴发生在LIGO的第五次科学运行和处女座的第一次科学运行。这次搜索包括22个GRB,这些GRB的数据来自LIGO/Virgo网络中的多个探测器。没有发现统计上显著的引力波候选者,参数检验表明在我们的伽玛暴样本中没有多余的弱引力波信号。90%~ C. L.在中子星-黑洞祖先模型假设下,我们的样本中伽玛暴的中位排斥距离为6.7 Mpc。

Implications of recoil kicks for black hole mergers from LIGO/Virgo catalogs
LIGO/Virgo合作的第一和第二个引力波瞬态目录包括$50$确认的合并事件,来自第一,第二和第三次观测运行的前半部分。我们计算反冲踢的分布赋予合并残余物和估计其保留概率在各种天体物理环境中的最大祖自旋($χ_{\rm max}$)的函数,假设LIGO/处女座二进制黑洞(BBH)合并催化的动态组装在一个致密的星团。我们发现,对于$0.1$,$0.3$,$0.5$,$0.8$的最大祖自旋,平均反冲分布分别在$150$ km s $^{-1}$,$250$ km s $^{-1}$,$350$ km s $^{-1}$,$600$ km s $^{-1}$附近达到峰值.只有逃逸速度为$\gtrsim 100$ km s $^{-1}$的环境,如在银河系核星团以及最大质量的球状星团和超级星团中发现的那样,才能有效地保留LIGO/室女座BBH人口的合并残余,即使是低祖先自旋($χ_{\rm max}=0.1$)。在高祖先自旋($χ_{\rm max}\gtrsim 0.5$)的情况下,只有质量最大的核星团才能保留合并产物。我们还发现,如果GW 170729,GW 190412,GW 190519和GW 190620的祖先是中等自旋($χ_{\rm max}\gtrsim 0.3$),而GW 190517的祖先是快速自旋($χ_{\rm max}\gtrsim 0.8$),则可以再现有效自…
