Understanding how Quantum chromodynamic (QCD) jets undergo energy loss in the presence of the Quark-Gluon Plasma (QGP) is one of the key theoretical and experimental challenges of the heavy ion programs at LHC,
CERN. Detailed insight into the interplay between parton energy loss and the way deconfined medium created in heavy-ion collisions expands is of great importance for improving the understanding of the jet
quenching phenomenon. In this exploratory study, we investigate the novel scaling features in the jet quenching parameter among the static and Bjorken expanding medium profiles for radiative and transverse
momentum broadened parton cascades. We shall see the impact of the expansion of the medium on the rapidity dependence of the jet nuclear modification factor as well as the jet elliptic flow followed by
comparison with the ATLAS, LHC data. Subsequently, we probe the angular structure for hard and soft momentum jets within a cone in expanding media. Finally, we discuss the importance and scope of our results on
the phenomenological description of the out-of-cone radiation and jet quenching.
