摘要

我们重新计算了轴向Bianchi I宇宙中运动源的漂移。我们的结果解决了Quercellini等人2009年的计算与Marcori等人2018年的计算之间长期存在的分歧，支持后者。这些计算对盖亚数据分析和宇宙学参数估计有潜在的影响。

Axial Bianchi I meets drifting extragalactic sources

We recompute ab initio the drift of comoving sources in axial Bianchi I universes. Our result resolves the long-standing disagreement between the computations by Quercellini et al from 2009 and by Marcori et al from 2018 in favor of the latter. These computations have a potential impact on Gaia data analysis and cosmological parameter estimation.
