论文摘要
我们使用与宇宙学的方法使用宇宙射线爆发（GRB）从观察性哈勃数据（OHD）中校准使用宇宙天文钟方法。通过使用高斯流程重建OHD，我们校准了Amati关系（$ e _ {\ rm p} $ - $ e _ {\ rm ISO} $），以使用A118数据集构造GRB Hubble图，并使用Markov Chain Monte Carlo Carlo Carlo Numerical Modect在平面空间中限制暗能量模型。在A118数据集中，与宇宙学无关的GRB $ 1.4 <Z \ leq8.2 $，以及IA型超新星（Sne IA）的万神殿样本，$ 0.01 <z \ leq2.3 $，我们获得了$ω_{\ rm M} $ 0.379^$ 0.379^$ $ = $ 0.379^$ $ = $ 0.379^{+0.033 { $0.701^{+0.0035}_{-0.0035}$, $w$ = $-1.25^{+0.14}_{-0.12}$, $w_a$ = $-0.84^{+0.81}_{-0.38}$ for the flat Chevallier-Polarski-Linder model at the 1$σ$ confidence level.我们发现没有明显的证据支持与标准$λ$ CDM模型的偏差。
We use a cosmology-independent method to calibrate gamma-ray burst (GRB) from the observational Hubble data (OHD) with the cosmic chronometers method. By using Gaussian Process to reconstruct OHD, we calibrate the Amati relation ($E_{\rm p}$--$E_{\rm iso}$) to construct a GRB Hubble diagram with the A118 data set, and constrain Dark Energy models in a flat space with the Markov Chain Monte Carlo numerical method. With the cosmology-independent GRBs at $1.4<z\leq8.2$ in the A118 data set and the Pantheon sample of type Ia supernovae (SNe Ia) at $0.01<z\leq2.3$, we obtained $Ω_{\rm m}$ = $0.379^{+0.033}_{-0.024}$, $h$ = $0.701^{+0.0035}_{-0.0035}$, $w$ = $-1.25^{+0.14}_{-0.12}$, $w_a$ = $-0.84^{+0.81}_{-0.38}$ for the flat Chevallier-Polarski-Linder model at the 1$σ$ confidence level. We find no significant evidence supporting deviations from the standard $Λ$CDM model.
