Abstract

It has been only sim 15 years since the discovery of dark energy although some may argue there were strong indications even earlier In the short time since measurements of type Ia supernovae indicated an accelerating universe many other techniques have now confirmed the acceleration is real The variety of ways in which dark energy has been confirmed is one of the reasons we are so confident in the statement that most of the energy in the universe is in a form we can not see except through its gravitational influence This review aims to summarise briefly the many varied ways we now have measured dark energy The fact that these different techniques all indicate that the simplest model remains the best—that dark energy contributes a constant background acceleration—is remarkable since each of these different types of measurements represented opportunities for this simplest model to fail Although we currently lack a compelling theoretical explanation for this acceleration any explanation will have to explain the wide variety of complementary observations that we review here This is an informal presentation following the lines of the talk I presented at the General Relativity and Gravitation GR20 conference in Warsaw in July 2013I’d like to thank the relatively unsung heroes of this field the observers and instrument designers who create the technology that enables us to have this wealth of observational data to challenge and inform our understanding of the universe Many thanks also to those who provided comments on drafts including Chris Blake Jason Dossett Dragan Huterer Catherine Heymans Anthea King Eric Linder Jochen Liske and David Parkinson TMD acknowledges the support of the Australian Research Council ARC through a Future Fellowship award FT100100595 and as part of the ARC Centre of Excellence for Allsky Astrophysics CAASTRO project CE110001020
