  The large statistics accumulated during the LHC Run-1 and Run-2 have provided
the unique opportunity to study the properties of the Quark-Gluon Plasma using
rare hard probes. The ALICE Collaboration has presented new results on the jet
shape observables in p--Pb and Pb--Pb collision. Using data from Run-2, the
elliptic flow of open and hidden charm mesons have been measured with much
better precision, confirming that charm quarks participate in the collective
dynamic expansion with the medium. In p--Pb collisions the absence of jet
quenching correlated with high event activity has been confirmed by a
self-normalized semi-inclusive hadron+jet measurement.
