Searches for new phenomena with the ATLAS detector

Many theories beyond the Standard Model (BSM) predict new phenomena accessible at the LHC which prevent the need of fine-tuning of the Higgs Boson mass, provide a candidate to explain dark matter, or expand the gauge sectors of the SM for example. The talk will focus on searches for new physics models, focusing on non-supersymmetric ones, which are performed using pp collision data collected by the ATLAS detector at the LHC with a centre-of-mass energy of 13 TeV.
