      abstract     = {Parton energy loss in the quark-gluon plasma (QGP) is
                      studied with a measurement of photon-tagged jet production
                      in 1.7 nb$^{-1}$ of Pb+Pb data and 260 pb$^{-1}$ of $pp$
                      data, both at $\sqrt{s_\mathrm{NN}} = 5.02$ TeV, with the
                      ATLAS detector. The process $pp \to \gamma$+jet+$X$ and its
                      analogue in Pb+Pb collisions is measured in events
                      containing an isolated photon with transverse momentum
                      ($p_\mathrm{T}$) above $50$ GeV and reported as a function
                      of jet $p_\mathrm{T}$. This selection results in a sample of
                      jets with a steeply falling $p_\mathrm{T}$ distribution that
                      are mostly initiated by the showering of quarks. The $pp$
                      and Pb+Pb measurements are used to report the nuclear
                      modification factor, $R_\mathrm{AA}$, and the fractional
                      energy loss, $S_\mathrm{loss}$, for photon-tagged jets. In
                      addition, the results are compared with the analogous ones
                      for inclusive jets, which have a significantly smaller
                      quark-initiated fraction. The $R_\mathrm{AA}$ and
                      $S_\mathrm{loss}$ values are found to be significantly
                      different between those for photon-tagged jets and inclusive
                      jets, demonstrating that energy loss in the QGP is sensitive
                      to the colour-charge of the initiating parton. The results
                      are also compared with a variety of theoretical models of
                      colour-charge-dependent energy loss.},
