Commissioning of the ATLAS tile calorimeter with cosmic ray and single beam data

The commissioning of the ATLAS detector at the Large Hadron Collider (LHC) has been the focus of an extensive program over several years. We present a summary of cosmic ray and single beam commissioning results with the ATLAS hadronic Tile Calorimeter (TileCal). The emphasis will be on understanding the energy and timing reconstruction, and validation of their calibration. Finally, electronic noise at the cell level is studied, and performance of calorimeter clusters is investigated.
