Abstract

We investigate some cosmological implications at the background level of the Bumblebee model. The phase-space, the critical points, and their stability are analyzed in detail, applying well-established dynamical system techniques. In addition, upon comparison to the available supernovae and Pantheon+SHOES data, the best-fit numerical value of the unique free parameter of the model is determined. We present graphical representations of key cosmological quantities as functions of redshift, including the deceleration parameter and the dark energy equation-of-state parameter. The statefinders and the age of the Universe are also computed. Finally, a comparison to the $Λ CDM$ model is made as well.

FLRW背景下大黄蜂理论的宇宙学意义

我们在大黄蜂模型的背景水平上研究了一些宇宙学意义。应用成熟的动力系统技术，详细分析了相空间、临界点及其稳定性。此外，通过与现有超新星和Pantheon+SHOES数据的比较，确定了模型唯一自由参数的最佳拟合数值。我们给出了关键宇宙学量作为红移函数的图形表示，包括减速参数和暗能量状态方程参数。还计算了状态查找器和宇宙的年龄。最后，还与Λ CDM $\Lambda{\rm CDM}$模型进行了比较。

期刊介绍： The journal Fortschritte der Physik - Progress of Physics is a pure online Journal (since 2013). Fortschritte der Physik - Progress of Physics is devoted to the theoretical and experimental studies of fundamental constituents of matter and their interactions e. g. elementary particle physics, classical and quantum field theory, the theory of gravitation and cosmology, quantum information, thermodynamics and statistics, laser physics and nonlinear dynamics, including chaos and quantum chaos. Generally the papers are review articles with a detailed survey on relevant publications, but original papers of general interest are also published.
