Abstract
Measurements of prompt-isolated photon production at hadron colliders provide a stringent test of perturbative QCD and can be used to constrain the gluon distribution functions inside the proton. In this article, the measurement of inclusive-photon cross-section ratio at $\sqrt{s}=8$ and $\sqrt{s}=13$ TeV is presented together with the isolated-photon plus jet cross section measurements at $\sqrt{s}=13$ TeV. The measurements use proton-proton collision data collected by the ATLAS experiment at the LHC.
