High momentum transfer processes can be reliably calculated by perturbative quantum chromodynamics (pQCD). Products of those hard processes, high transverse momentum particles, jets, and heavy quarks (hard probes), interact with the quark-gluon plasma (QGP) created in relativistic heavy-ion collisions. Properties of the QGP can be studied by comparing hard probe measurements in heavy-ion collisions to those in p+p collisions or from pQCD calculations. I will present recent results from STAR on hard probe measurements, including a wide range of observables: heavy flavor, dijet transverse momentum imbalance, hadron-jet correlations, γ-jet correlations, and dihadron correlations. I will discuss what we have learned from these measurements.
