摘要：
We work on the reconstruction scenario of pilgrim dark energy (PDE) in f(T,TG). In PDE model it is assumed that a repulsive force that is accelerating the Universe is phantom type with (wDE<−1) and it is so strong that prevents formation of the black hole. We construct the f(T,TG) models and correspondingly evaluate equation of state parameter for various choices of scale factor. Also, we assume polynomial form of f(T,TG) in terms of cosmic time and reconstruct H and wDE in this manner. Through discussion, it is concluded that PDE shows aggressive phantom-like behavior for s=−2 in f(T,TG) gravity.
