      abstract     = {A search for associated production of a heavy $Z'$ boson
                      with a top-quark or a top-antitop-quark pair, and decaying
                      into a $t\bar{t}$ pair is presented. The search uses the
                      data recorded by the ATLAS detector in $pp$ collisions at
                      $\sqrt{s}= 13$ TeV at the Large Hadron Collider during the
                      years 2015-2018, corresponding to an integrated luminosity
                      of 139 fb$^{-1}$. Events containing exactly one electron or
                      muon are selected. The two top quarks from the resonance
                      decay are reconstructed using jets clustered with a large
                      radius parameter of $R=1$. The invariant mass spectrum of
                      the two top quark candidates is used to search for a
                      resonance signal in the range of 1.0 TeV to 3.2 TeV. The
                      presence of a signal is examined using an approach with
                      minimal model dependence followed by a model-dependent
                      interpretation. No significant excess is observed over the
                      background expectation. Upper limits on the production cross
                      section times branching ratio at 95\% confidence level are
                      provided as a function of $Z^\prime$ mass between 1.0 TeV
                      and 3.0 TeV, based on a simplified $Z^\prime$ production
                      model. The observed (expected) limits range from 21 (14) fb
                      to 119 (86) fb depending on the choice of model parameters.},
