膨胀宇宙中信号传播特征的暗能量效应

The dark energy effect as manifestation of the signal propagation features in expanding Universe

L. M. Tomilchik

摘要:

本文从光锥方程出发,通过保角群变换,直接导出了信号在膨胀空间中随距离变化的显式红移公式,以及哈勃定律的表达式。所获得的关系与表示为不涉及其他参数,但缩放因子$c H^{-1}_0$的红移的显式函数的光度距离。这些关系表示在一个纯粹的运动学的方式,并在一个完整的协议与观测,揭示过渡的超星系加速膨胀(暗能量效应)。

英文摘要:

The formula describing the explicit red-shift dependence for the distance covered by a signal in the expanding space, and also the expressions for Hubble law have been derived directly from the conformal group transformations taking into account the light-cone equation. The obtained relations are associated with the luminosity distance represented as an explicit function of the red shift involving no other parameters but the scaling factor $c H^{-1}_0$. These relations represent in a pure kinematical way and in a complete agreement with observations, the revealed transition of the Metagalaxy to accelerated expansion (the dark energy effect).
