论文摘要
我们从最新的观察数据中研究了可变的Chaplygin气体模型的宇宙学限制：SCP Union 2.1 IA型超新星（SNE IA）的汇编数据集，SNE IA的Pantheon样品，Snema sne ia的Platinum platinum platinum platinum platinum的γ射线爆发样本（GRB）和GWTC-3的GRAVITION波浪Merger事件的GWTC-3。可变的Chaplygin气体是一种相互作用的暗物质和暗能量的模型，从尘土主导的时代到以典型为主的时代进行了插值。可变的Chaplygin气模型显示与IA型超新星和重力合并数据兼容。使用万神殿样本，我们对宇宙学参数$ b_s $和$ n $的限制更加严格。通过在Pantheon样本中使用Markov Chain Monte Carlo（MCMC）方法，我们获得$ b_s $ = 0.108 $ \ pm $ \ pm $ 0.034，n = 1.157 $ \ pm $ \ pm $ 0.513和$ h_0 $ = 70.020 $ \ 70.020 $ \ pm $ 0.407 $ h_0 $ = 70.41 $ \ pm $ 0.67}，在GWTC-3上，我们获得$ b_s $ = 0.130 $ \ pm $ 0.076，n = 0.897 $ \ pm $ \ pm $ 1.182和$ h_0 $ = 69.838 $ \ pm pm $ 3.007。上述数据集的组合约束为$ b_s $ = 0.11 $ \ pm $ 0.03，n = 1.14 $ \ pm $ 0.36和$ h_0 $ = 70.34 $ \ pm $ 0.61
We investigate the cosmological constraints on the Variable Chaplygin gas model from the latest observational data: SCP Union 2.1 compilation dataset of Type Ia supernovae (SNe Ia), Pantheon sample of SNe Ia, Platinum Sample of Gamma Ray Bursts (GRB) and GWTC-3 of gravitational wave merger events. Variable Chaplygin gas is a model of interacting dark matter and dark energy, which interpolates from a dust-dominated era to a quintessence-dominated era. The Variable Chaplygin gas model is shown to be compatible with Type Ia Supernovae and gravitational merger data. We have obtained tighter constraints on cosmological parameters $B_s$ and $n$, using the Pantheon sample. By using the Markov chain Monte Carlo (MCMC) method on the Pantheon sample, we obtain $B_s$=0.108 $\pm$ 0.034, n=1.157 $\pm$ 0.513 and $H_0$=70.020 $\pm$ 0.407, for GRBs, we obtain $B_s$=0.20 $\pm$ 0.11, n=1.45 $\pm$ 1.40 and $H_0$=70.41 $\pm$ 0.67} and on GWTC-3, we obtain $B_s$=0.130 $\pm$ 0.076, n=0.897 $\pm$ 1.182 and $H_0$=69.838 $\pm$ 3.007. The combined constraints from the above data sets are $B_s$=0.11 $\pm$ 0.03, n=1.14 $\pm$ 0.36 and $H_0$=70.34 $\pm$ 0.61
