DOI: 10.1007/s12648-017-1126-8
Abstract: Cosmological model with viscous generalized Chaplygin gas (in short, VGCG) is considered here to determine observational constraints on its equation of state parameters (in short, EoS) from background data. These data consists of $$H(z)-z$$H(z)-z (OHD)… read more here.

DOI: 10.1088/1475-7516/2023/04/052
Abstract: The fact that Einstein's equations connect the space-time geometry to the total matter content of the cosmic substratum, but not to individual contributions of the matter species, can be translated into a degeneracy in the… read more here.
