Searches for New Phenomena with ATLAS at sqrt(s)=8 TeV

ATLAS has carried out a wide range of searches for new phenomena with many different final states. In this talk, we report on recent searches with 8 TeV data. Among the topics covered will be heavy resonances decaying into pairs of jets, leptons, lepton and jet, photon and jet, as well as dibosons. Dark matter searches were carried out in events with large missing transverse missing momentum and a single jet, photon or W/Z boson. Many of the above final states have also been interpreted in the context of models with large or warped extra dimensions. Finally, events with multileptons have provided model independent constraints on new physics.
