Observing Signals of Extra Spatial Dimensions with ATLAS

Thanks to the high collision energy and luminosity of the LHC, the ATLAS detector will be capable of revealing the existence of extra spatial dimensions in some substantial region of parameter space. I shall summarize recent studies from the collaboration on different possible signals predicted by models where the dimensions are "large", where they are of size ~TeV^-1 or where they are “warped”. I shall also mention studies on the potential for black hole production and detection.
