Query: Bulk medium evolution has considerable effects on jet observables!   We consider the case, in QCD, of a single jet propagating within a strongly
interacting fluid, of finite extent. Interactions lead to the appearance of a
source of energy-momentum within the fluid. The remnant jet that escapes the
container is analyzed along with portions of the medium excited by the jet. We
study the effect of a static versus a semi-realistic expanding medium, with
jets traveling inward versus outward. We consider the medium response via
recoils in partonic scatterings based on a weakly-coupled description and its
combination with hydrodynamical medium response based on a strongly-coupled
description, followed by incorporation into a jet. The effects of these limits
on the reconstructed energy, momentum and mass of the jet, as a function of the
angle away from the original parton direction are studied. It is demonstrated
that different flow velocity configurations in the medium produce considerable
differences in jet observables. This work highlights the importance of accurate
dynamical modeling of the soft medium as a foundation on which to calculate jet
modification, and casts skepticism on results obtained without such modeling.
