论文摘要
考虑到在de安静的宇宙中的纵向多普勒效应，获得了新的红移公式，其中相对的测量运动受我们新的de Sitter相对性的洛伦兹异态分析的控制[I. I. I. cot \ u aescu，{ur。物理。 J. C} {\ bf 77}（2017）485]。该公式以非平凡的方式结合了Lama \'Itre定律所著名的宇宙学贡献与源相对于固定观察者的相对运动的宇宙学贡献，例如在Sitter相对性中，而不是特殊相对论。讨论了其他相关数量作为分散关系，光子的传播时间以及观察时源和观察者之间的真实距离，以指出其在DE Sitter相对性中的特定特征。
A new redshift formula is obtained considering the longitudinal Doppler effect in the de Sitter expanding universe where the relative geodesic motion is governed by the Lorenzian isometries of our new de Sitter relativity [I. I. Cot\u aescu, {Eur. Phys. J. C} {\bf 77} (2017) 485]. This formula combines in a non-trivial manner the well-known cosmological contribution given by Lama\' itre's law with that of the relative motion of the source with respect to a fixed observer as in de Sitter relativity instead of special relativity. Other related quantities as the dispersion relation, the propagation time of the photon and the real distance between source and observer at the moment of observation are discussed pointing out their specific features in the de Sitter relativity.
