We present a measurement of the Hubble constant H 0 using the gravitational wave (GW) event GW190814, which resulted from the coalescence of a 23 M ⊙ black hole with a 2.6 M ⊙ compact object, as a standard siren. No compelling electromagnetic counterpart has been identified for this event; thus our analysis accounts for thousands of potential host galaxies within a statistical framework. The redshift information is obtained from the photometric redshift (photo- z ) catalog from the Dark Energy Survey. The luminosity distance is provided by the LIGO/Virgo gravitational wave sky map. Since this GW event has the second-smallest localization volume after GW170817, GW190814 is likely to provide the best constraint on cosmology from a single standard siren without identifying an electromagnetic counterpart. Our analysis uses photo- z probability distribution functions and corrects for photo- z biases. We also reana...

LIGO /处女座引力波紧凑物体合并GW190814和暗能量调查星系对哈勃常数的统计标准警笛测量

我们使用引力波(GW)事件GW190814给出了对哈勃常数H 0的测量,该事件是由23 M⊙黑洞与2.6 M M紧凑物体作为标准警报器合并而成的。尚未发现与此事件相关的引人注目的电磁对手;因此,我们的分析在一个统计框架内解释了数千个潜在的宿主星系。红移信息是从“暗能量调查”的光度红移(photo-z)目录中获得的。亮度距离由LIGO /处女座引力波天空图提供。由于此GW事件的定位量仅次于GW170817,仅次于GW170,因此GW190814可能会在不识别电磁对等物的情况下,从单个标准警报器提供对宇宙学的最佳约束。我们的分析使用了photoz概率分布函数并校正了photoz偏差。我们还重新
