متن کاملInflationary paradigm in trouble after Planck 2013
Article history: Received 9 April 2013 Received in revised form 8 May 2013 Accepted 9 May 2013 Available online 14 May 2013 Editor: M. Cvetič Recent results from the Planck satellite combined with earlier observations from WMAP, ACT, SPT and other experiments eliminate a wide spectrum of more complex inflationary models and favor models with a single scalar field, as reported by the Planck Coll...
متن کاملPlanck scale inflationary spectra from quantum gravity
We derive the semiclassical evolution of massless minimally coupled scalar matter in the de Sitter space-time from the Born-Oppenheimer reduction of the Wheeler-DeWitt equation. We show that the dynamics of trans-Planckian modes can be cast in the form of an effective modified dispersion relation and that high energy corrections in the power spectrum of the cosmic microwave background radiation...
متن کاملPlanck 2013 results . XXVIII . The Planck Catalogue of Compact Sources
The Planck Catalogue of Compact Sources (PCCS) is the catalogue of sources detected in the first 15 months of Planck operations, the “nominal” mission. It consists of nine single-frequency catalogues of compact sources, both Galactic and extragalactic, detected over the entire sky. The PCCS covers the frequency range 30–857 GHz with higher sensitivity (it is 90 % complete at 180 mJy in the best...
متن کاملPlanck 2013 results . XXIX . Planck catalogue of Sunyaev – Zeldovich sources
We describe the all-sky Planck catalogue of clusters and cluster candidates derived from Sunyaev–Zeldovich (SZ) effect detections using the first 15.5 months of Planck satellite observations. The catalogue contains 1227 entries, making it over six times the size of the Planck Early SZ (ESZ) sample and the largest SZ-selected catalogue to date. It contains 861 confirmed clusters, of which 178 ha...
