Cosmological evolution of generalized ghost pilgrim dark energy in f (T) gravity

摘要

We explore the phenomenon that phantom-like dark energy prevents the formation of black holes by assuming the generalized ghost version of pilgrim dark energy in the background of generalized teleparallel gravity. In this scenario, we construct f (T) model for explaining the evolutionary behavior of equation of state parameter, omega(A) - omega(A)' and r - s planes. We discuss these cosmological parameters graphically by taking different values of redshift parameter and pilgrim dark energy parameter. It is found that the equation of state parameter shows phantom like behavior while omega(A) - omega(A)' plane possesses thawing region for some particular values of pilgrim dark energy parameter. The statefinder parameters in r - s plane indicate the behavior of quintessence and phantom models. Finally, we discuss the first and second laws of thermodynamics and investigate the behavior of entropy production term.
