Detection of higher order modes of gravitational waves in third-generation (3G) ground-based detectors such as Cosmic Explorer and Einstein Telescope is explored. Using the astrophysical population of binary black holes based on events reported in the second gravitational wave catalog by Laser Interferometer Gravitational Wave Observatory (LIGO) and Virgo (GWTC-2), in conjunction with the Madau-Dickinson model for redshift evolution of the binary black hole mergers, we assess the detectability of these higher order modes using a network consisting of three third-generation detectors. We find that the two subleading modes [(3,3) and (4,4)] can be detected in approximately 30% of the population with a network signal-to-noise ratio of 3 or more, and for nearly 10% of the sources, the five leading modes will be detectable. Besides, a study concerning the effect of binary's mass ratio and its orbital inclination with the observer's line-of-sight in detecting various modes is presented. For a few selected events of the LIGO-Virgo catalog, we identify the modes that would have been detected if a third-generation detector was operational when these events were recorded. We also compute the detectability of higher modes by Voyager and find that only $\sim$ 6 and 2% of the detectable population will have an associated detection of (3,3) and (4,4) modes, respectively. Observing these higher order modes in the 3G era would have a huge impact on the science possible with these detectors ranging from astrophysics and cosmology to testing strong-field gravity.

Bose-Einstein-condensed scalar field dark matter and the gravitational wave background from inflation: new cosmological constraints and its detectability by LIGO
我们考虑了另一种冷暗物质候选者，超轻玻色子（$m>10^{-22}$ eV）描述的复杂标量场（SFDM）与全球U（1）对称性，与共动粒子数密度守恒粒子生产后，在标准的再加热。我们允许排斥性的自我作用。在Lambda-SFDM宇宙中，SFDM开始是相对论性的，从刚性（w=1）演化到辐射状（w=1/3），在后期变成非相对论性（w=0）。因此，一个僵硬的SFDM主导的时代之前，熟悉的辐射主导的时代。因此，SFDM粒子质量$m$和四次自相互作用强度λ受到宇宙学观测量的约束，N_{eff}是BBN期间中微子种类的有效数量，z_{eq}是物质辐射等效红移。由于暴胀产生的随机引力波背景（SGWB）在刚性SFDM主导的时期被放大，它也可以贡献足够大的辐射分量来影响这些观测值。值得注意的是，这种放大使得该SGWB可以通过当前的GW实验检测到，例如，aLIGO/室女座和LISA，满足宇宙学约束的Lambda-SFDM模型，再热温度T_{re}和目前允许的张量标量比$r$值的范围。对于给定的r和$λ/(mc^2)^2$，每个T_{re}的边际允许的Lambda-SFDM模型具有满足宇宙学约束的最小m。例如，对于r=0.01和$λ/(mc^2)^2=10^{-18}$ eV $^{-1}$ cm $^3$的边际允许模型，aLIGO O 1运行的零检测排除了8.75*10^3< T_{re}（GeV）<1.…
