Variable Chaplygin Gas: Contraining parameters using FRBs
Abstract
We investigate cosmological constraints on the Variable Chaplygin gas model parameters with latest observational data of the Fast Radio Bursts and compare the results with previous constraints obtained using SNe Ia (Pantheon+SHOES), Gamma Ray Bursts, Baryon Acoustic Oscillations and Hubble parameter observational data. The Variable Chaplygin gas model is shown to be compatible with these datasets.} We have obtained tighter constraints on model parameters and , using the FRB data set. By using the Markov chain Monte Carlo (MCMC) method we obtain, = , and = with the SNe Ia data set, = , and with the FRB data set, = , and = with the BAO data set, = , and = with the H(z) data set and = , and = with the GRB data set . A good agreement for is observed from these data sets.
