Abstract
We present a study of the impact of the expansion of deconfined medium on\nsingle-gluon emission spectra and the jet suppression factor ($Q_{AA}$) within\nthe BDMPS-Z formalism. These quantities are calculated for three types of media\n(static medium, exponentially decaying medium and Bjorken expanding medium).\nThe distribution of medium-induced gluons and the jet $Q_{AA}$ are calculated\nusing the evaluation of in-medium evolution with splitting kernels derived from\nthe gluon emission spectra. Scaling behavior of splitting kernels is derived\nfor low-x and high-x regimes in the asymptote of large times and its impact on\nthe resulting jet $Q_{AA}$ is discussed. For the full phase space of the\nradiation, the scaling of jet $Q_{AA}$ with an effective quenching parameter is\npresented.\n
