宇宙学红移与光子标度因子的关系

The relation between cosmological redshift and scale factor for photons

Shuxun Tian

摘要:

宇宙学常数问题已成为现代宇宙学中最重要的问题之一。在本文中,我们试图构建一个模型,可以避免宇宙学常数的问题,并有可能解释在光度距离和角直径距离测量通道的宇宙的明显的后期加速膨胀。在我们的模型中,核心是修正宇宙学红移与光子标度因子之间的关系。我们指出三种方法来检验我们的假设:超新星的时间膨胀;中子星双星系统发射的引力波及其电磁波;以及Sandage-Loeb效应。所有这些方法现在或在不久的将来都是可行的。

英文摘要:

The cosmological constant problem has become one of the most important ones in modern cosmology. In this paper, we try to construct a model that can avoid the cosmological constant problem and have the potential to explain the apparent late-time accelerating expansion of the universe in both luminosity distance and angular diameter distance measurement channels. In our model, the core is to modify the relation between cosmological redshift and scale factor for photons. We point out three ways to test our hypothesis: the supernova time dilation; the gravitational waves and its electromagnetic counterparts emitted by the binary neutron star systems; and the Sandage--Loeb effect. All of this method is feasible now or in the near future.
