宇宙项影响引力透镜吗?

Does Cosmological Term Influence Gravitational Lensing?

I. B. Khriplovich, A. A. Pomeransky

摘要:

我们分析了在宇宙学项存在下星系或星系团对光的弯曲。转到Friedmann-Robertson-Walker坐标系,实际上用于描述实际观测,我们证明了宇宙学常数实际上不影响透镜效应。

英文摘要:

We analyze the bending of light by galaxies or clusters of galaxies in the presence of the cosmological term. Going over to the Friedmann-Robertson-Walker coordinates, used in fact for the description of actual observations, we demonstrate that the cosmological constant does not influence practically the lensing effect.
