论文摘要
为了重新创建宇宙学模型,我们在修饰的远程高斯 - 骨网重力中采用了参数化方法。应用参数化方法研究宇宙学模型很有趣。使用这种方法的真正好处是可以合并观察数据以检查宇宙学模型。检查了几个宇宙学参数,例如哈勃参数(H),减速参数(Q)和状态(EOS)参数方程(W)。获得的结果与传统情况下的宇宙学发现一致。已经观察到了从减速阶段到宇宙进化加速阶段的过渡情况。 EOS参数也处于典型阶段,它驱动了宇宙的加速膨胀。同样,我们考虑违反强能量条件的行为,这在修改后的重力理论的背景下变得不可避免。最后,我们进行了OM(Z)诊断,并通过使用宇宙学观察结果的数据获得了宇宙的年龄。
To recreate the cosmological models, we employed the parametrization approach in modified teleparallel Gauss-Bonnet gravity. It has been interesting to apply the parametrization approach to investigate cosmological models. The real benefit of using this method is that the observational data may be incorporated to examine the cosmological models. Several cosmological parameters were examined, such as the Hubble parameter (H), the deceleration parameter (q), and the equation of state (EoS) parameter (w). The results obtained are consistent with recent cosmological findings in the conventional scenario. A transition scenario from a decelerating stage to an accelerating stage of cosmic evolution has been observed. The EoS parameter is also in the quintessence phase, which drives the accelerating expansion of the Universe. Also, we look at the violation of strong energy condition, which has become inevitable in the context of modified gravitational theory. Finally, we have performed the Om(z) diagnostic and also obtained the age of the Universe by using the data from the cosmological observations.
