“…Currently, works have been done on the CG and the GCG models [12] and many authors have attempted to constrain them by using various observational data, such as Sne Ia [13,14,15,16,17,18], the CMBR [18,19,20], the gamma-ray bursts [21], the gravitational lensing [15,17,22], the X-ray gas mass fraction of clusters [14,15,16], the large scale structure [18,23], the age of high-redshift objects [24], and the Hubble parameter versus redshift [25].…”
