Abstract: Dynamical aspects of an anisotropic cosmological model are investigated in an extended gravity theory. A hybrid scale factor is employed to investigate the cosmic dynamics. The hybrid scale factor simulates a cosmic transit behaviour from… read more here.

DOI: 10.1142/s0217751x20400576
Abstract: The new result on Horndeski model asymptotic at Galaxy cluster scales is presented. As the obtained constraint for Λeff has the same order as for the real cosmological constant we demonstrate that ... read more here.
