论文摘要
重力的替代理论可以预测重力波（GW）到时空传播的修饰。此类理论的吸烟枪预测之一是GW光度距离与GW源的变化是红移相对于电磁（EM）光度距离的函数的函数。我们通过结合EM和GW观测值来解决重力波的传播，对一般相对论的多通信测试，从没有EM对应物的GW来源解决这些问题（也称为暗标准警报器）。通过使用可从Baryon声学振荡测量值访问的几何距离与GW来源的光度距离测量之间的关系，我们可以通过不知名的红移的GW源来衡量与相对性的一般理论的任何偏差，这些偏差源将被GW检测器网络（例如Ligo，civirgo，virgo，virgo，virgo，virgo，virgo and kagra和kagrra）检测到。使用此技术，可以将摩擦术语的基准价值测量为精确$ξ_0= 0.98^{+0.04} _ { - 0.23} $在红外依赖，宇宙学参数和GW偏见参数和$ sim 3500 $ sim 3500 $ $ thard Standard of MassEs $ 30 clistion $ 30 $ 30 clistionals $ 30.红移$ z = 0.5 $。对于固定的红移依赖性，$ξ_0= 0.99^{+0.02} _ { - 0.02} $的值可以用类似数量的暗架来测量。我们的方法在可检测到的下一代GW探测器（例如Lisa，Einstein望远镜和宇宙资源管理器）中可检测到的大量深色标准警笛中的应用将允许与使用明亮标准警报器的使用相比更高的准确性。
Alternative theories of gravity predict modifications in the propagation of gravitational waves (GW) through space-time. One of the smoking-gun predictions of such theories is the change in the GW luminosity distance to GW sources as a function of redshift relative to the electromagnetic (EM) luminosity distance expected from EM probes. We propose a multi-messenger test of the theory of general relativity from the propagation of gravitational waves by combining EM and GW observations to resolve these issues from GW sources without EM counterparts (which are also referred to as dark standard sirens). By using the relation between the geometric distances accessible from baryon acoustic oscillation measurements, and luminosity distance measurements from the GW sources, we can measure any deviation from the general theory of relativity via the GW sources of unknown redshift that will be detectable by networks of GW detectors such as LIGO, Virgo, and KAGRA. Using this technique, the fiducial value of the frictional term can be measured to a precision $Ξ_0=0.98^{+0.04}_{-0.23}$ after marginalizing over redshift dependence, cosmological parameters, and GW bias parameters with $\sim 3500$ dark standard sirens of masses $30\,\rm M_\odot$ each distributed up to redshift $z=0.5$. For a fixed redshift dependence, a value of $Ξ_0=0.99^{+0.02}_{-0.02}$ can be measured with a similar number of dark sirens. Application of our methodology to the far more numerous dark standard sirens detectable with next generation GW detectors, such as LISA, Einstein Telescope and Cosmic Explorer, will allow achievement of higher accuracy than possible from use of bright standard sirens.
