  We compute holographically the expectation value of the energy density
sourced, in a strongly-coupled CFT, by a quark with large but finite mass (or
equivalently, small but finite Compton radius) undergoing arbitrary motion. The
resulting gluonic profile has two surprising features in the far region. First,
besides the expected radiation, it contains a component that is attributable to
the `intrinsic' or `near' field of the quark, and nevertheless falls off as the
square of the distance. Second, even at distances much larger than the size of
the quark, it differs from the profile set up by a pointlike quark. We explain
how this second feature provides a useful case study for the UV/IR connection
in a dynamical setting. We also examine some specific sample trajectories,
including uniform circular motion and harmonic oscillation, where features such
as the extent of the region with negative energy are found to vary with the
quark mass.
