The seminar presents new ATLAS results involving photons. Reported are a search for the three-body decay of the Higgs boson into a low-mass lepton pair and a photon, a search for invisible particle production associated with a Higgs boson decaying into two photons, and a search for a heavy diphoton resonance. All results are based on the full Run-2 dataset.
