Abstract：
With a multi-phase transport (AMPT) model, a γ-jet with known production point and momentum is triggered to search for the origin of double-peak structure in di-hadron azimuthal correlation in central Au+Au collisions at RHIC energy. The different configurations of triggered γ-jet produce different shapes of medium responses. The key of the double-peak structure is found to be a strong shadowing effect of dense core, which is related to transverse expansion and radial flow of partonic matter.
