  Jets are multi-partonic systems that develop before interactions with the
quark-gluon plasma set in and lead to energy loss and modifications of their
substructure. Jet modification depends on the degree to which the medium can
resolve the internal jet structure that is dictated by the physics of coherence
governed by a critical angle $\theta_c$. Using resummed quenching weights that
incorporate the IOE framework for medium-induced radiation and embedding the
system into a realistic heavy-ion environment we compute the dependence of jet
suppression on the cone angle $R$ of the jet, both at RHIC and the LHC. At RHIC
kinematics we see a very mild cone angle dependence for the range of $R$
studied, similar to what was found at the LHC. We also present results for the
jet azimuthal anisotropy $v_2$ as a function of $R$. We observe that as
centrality is decreased, $v_2$ for moderate $R$ jets sequentially collapse
towards the result for small $R = 0.1$. The reason of this sequential grouping
is the evolution of $\theta_c$ with centrality due to its strong dependence on
the in-medium traversed length. For jets with $R > \theta_c$, traversing
shorter lengths within the medium will make a larger difference than for jets
with $R < \theta_c$, since the size of the resolved phase-space over which
quenching weights are resummed will be reduced. For this reason, $v_2(R)$ is
quite sensitive to the typical value of $\theta_c$ at a given centrality.
