Recently, the theory of jet quenching has been extended to the case of hydrodynamical evolving matter. Here, we present the latest developments of the this toolkit, which takes into account both flow and anisotropy of the matter. First, we study the anisotropic structure of a static medium in the dense regime, where the ressummation of multiple in-medium scatterings is necessary. We will focus on the modifications to the single gluon production rate inside anisotropic matter. Second, we show the effect of the interplay between the flow and anisotropy of the matter, both for the jet momentum broadening and medium-induced branching, treating the interactions within opacity expansion. We will show that the mutual effect of the transverse flow and matter gradients results in a substantial rescaling of such fundamental objects as jet quenching parameter and energy loss rate, leading to multiple phenomenological implications.
