√
sNN = 5.02 TeV, the ATLAS detector has performed
measurements of exclusive dimuon production, light-by-light scattering (via exclusive diphoton production),
and photo-nuclear dijet production. These are all important examples of ultraperipheral collisions, where the nuclei do
not interact hadronically. A recent study of the opening angles of dimuons produced in hadronic heavy-ion collisions,
after subtracting heavy-flavor backgrounds, demonstrates that the dimuons carry information correlated with the overlap
geometry, potentially about the density of charges in the QGP itself.},
