Measurements of Higgs boson properties in the $H \rightarrow ZZ^* \rightarrow 4\ell$ and $H \rightarrow \gamma\gamma$ channels at $\sqrt{s}=13$ TeV using the ATLAS detector

<!--HTML--><p>Recent measurements of the Higgs boson properties in the four lepton and di-photon channels for 36.1 fb$^{-1}$ of pp collisions at 13 TeV using the ATLAS detector will be presented. The measurements include the Higgs boson mass as well as inclusive, fiducial, differential and, so-called, simplified template cross sections. Constraints on Higgs boson couplings are derived and interpreted within the Standard Model and various extensions.</p>
