标题： The motion of galaxy clusters in inhomogeneous cosmologies

摘要： 勒梅特-托尔曼-邦迪非均匀时空可以作为宇宙学模型来解释Ia型超新星数据。 然而，这种模型也会导致星系团相对于宇宙微波背景的高速运动。 这些速度可以通过动力学苏尼亚耶夫-泽尔多维奇效应进行测量。 本文提出了对该模型中星系团速度随红移变化的计算。 显示英文摘要

摘要： Lemaitre-Tolman-Bondi inhomogeneous spacetimes can be used as a cosmological model to account for the type Ia supernova data. However, such models also give rise to large velocities of galaxy clusters with respect to the cosmic microwave background. Those velocities can be measured using the kinematic Sunyaev-Zeldovich effect. This paper presents a calculation of galaxy cluster velocities as a function of redshift for such a model.
