Abstract

This work is based on pilgrim dark energy conjecture which states that phantom-like dark energy possesses the enough resistive force to preclude the formation of black hole. The non-flat geometry is considered which contains the interacting generalized ghost pilgrim dark energy with cold dark matter. Some well-known cosmological parameters (evolution parameter ($$\omega _{\Lambda }$$) and squared speed of sound) and planes ($$\omega _{\Lambda }$$–$$\omega _{\Lambda }'$$ and statefinder) are constructed in this scenario. The discussion of these parameters is totally done through pilgrim dark energy parameter ($$u$$) and interacting parameter ($$d^2$$). It is interesting to mention here that the analysis of evolution parameter supports the conjecture of pilgrim dark energy. Also, this model remains stable against small perturbation in most of the cases of $$u$$ and $$d^2$$. Further, the cosmological planes correspond to $$\Lambda $$CDM limit as well as different well-known dark energy models.
