Such bispectrum estimators are expected to continue to provide the best constraints on the non-Gaussian parameters in future observations. We review and compare the theoretical and observational problems, current results and future prospects for the detection of a non-vanishing primordial component in the bispectrum of the Cosmic Microwave Background and large-scale structure, and the relation to specific predictions from different inflationary models.", "revisions": [ { "version": "v1", "updated": "2010-01-25T23:04:56.000Z" } ], "analyses": { "keywords": [ "cosmic microwave background", "bispectrum measurements", "large-scale structure", "primordial non-gaussianity", "non-gaussian initial conditions" ], "tags": [ "review article", "journal article" ], "publication": { "doi": "10.1155/2010/980523", "journal": "Advances in Astronomy", "year": 2010, "volume": 2010, "pages": 980523 }, "note": { "typesetting": "TeX", "pages": 82, "language": "en", "license": "arXiv", "status": "editable", "inspire": 843475, "adsabs": "2010AdAst2010E..73L" } } }
