Query: Heavy quarks and jets as probes of the QGP   The Quark-Gluon Plasma (QGP), a QCD state of matter created in
ultra-relativistic heavy-ion collisions, has remarkable properties as a low
shear viscosity over entropy ratio. Through the detection of multi-particle
production, the bulk debris of the collision, these so-called soft probes have
provided quantitative insight into the created matter. However, its fast
evolution and thermalization properties remain elusive to the soft sector. Only
the usage of high momentum objects as probes of the QGP can unveil its
constituents at the different wavelengths. In this review, we attempt to
provide a comprehensive picture of what was, so far, possible to withdraw given
our current theoretical understanding of jets, heavy-flavor, and quarkonia. We
will bridge the resulting qualitative picture to the experimental observations
done at both the LHC and RHIC. We will focus on the phenomenological
description of experimental observations, provide a brief analytical summary of
the description of hard probes, and an outlook towards the main difficulties we
will need to surpass in the following years. To benchmark QGP-related effects,
we will also address nuclear modifications to the initial state and
hadronization effects.
