      abstract     = {Measurements of differential cross sections are presented
                      for inclusive isolated-photon production in pp collisions at
                      a centre-of-mass energy of 13 TeV provided by the LHC and
                      using 139 fb$^{−1}$ of data recorded by the ATLAS
                      experiment. The cross sections are measured as functions of
                      the photon transverse energy in different regions of photon
                      pseudorapidity. The photons are required to be isolated by
                      means of a fixed-cone method with two different cone radii.
                      The dependence of the inclusive-photon production on the
                      photon isolation is investigated by measuring the fiducial
                      cross sections as functions of the isolation-cone radius and
                      the ratios of the differential cross sections with different
                      radii in different regions of photon pseudorapidity. The
                      results presented in this paper constitute an improvement
                      with respect to those published by ATLAS earlier: the
                      measurements are provided for different isolation radii and
                      with a more granular segmentation in photon pseudorapidity
                      that can be exploited in improving the determination of the
                      proton parton distribution functions. These improvements
                      provide a more in-depth test of the theoretical predictions.
                      Next-to-leading-order QCD predictions from JETPHOX and
                      SHERPA and next-to-next-to-leading-order QCD predictions
                      from NNLOJET are compared to the measurements, using several
                      parameterisations of the proton parton distribution
                      functions. The measured cross sections are well described by
                      the fixed-order QCD predictions within the experimental and
                      theoretical uncertainties in most of the investigated
                      phase-space region.[graphic not available: see fulltext]},
