      abstract     = {A search for the associated production of a heavy resonance
                      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
                      $\sqrt{s}= 13$ $\text {TeV}$ at the Large Hadron Collider
                      during the years 2015–2018, corresponding to an integrated
                      luminosity of 139 $\text {fb}^{-1}$. Events containing
                      exactly one electron or muon are selected. The two
                      hadronically decaying 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 $\text {TeV}$ to 3.2 $\text
                      {TeV}$. 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 for a heavy $Z^\prime $ boson
                      based on a simplified model, for $Z^\prime $ mass between
                      1.0 $\text {TeV}$ and 3.0 $\text {TeV}$. The observed
                      (expected) limits range from 21 (14) fb to 119 (86) fb
                      depending on the choice of model parameters.},
