SIGNS AND COSMOLOGY [PDF]
International Journal of Modern Physics D, 2012 Using a new effective action predicted from quantum gravity where the sign of the Euclidean Einstein action is reversed, we discuss Wentzel–Kramers–Brillouin (WKB) solutions in quantum cosmology and predict that this sign change might explain the origin of phantom scalars.

, 2013 This paper presents the first cosmological results based on Planck measurements of the cosmic microwave background (CMB) temperature and lensing-potential power spectra. We find that the Planck spectra at high multipoles (l greater than or similar to 40) P. Ade, N. Aghanim, C. Armitage-Caplan, M. Arnaud, M. Ashdown, F. Atrio-Barandela, J. Aumont, C. Baccigalupi, A.

Entropy, 2023 We review the main aspects of geometrothermodynamics, a formalism that uses contact geometry and Riemannian geometry to describe the properties of thermodynamic systems. We show how to handle in a geometric way the invariance of classical thermodynamics with respect to Legendre transformations, which means that the properties of the systems do not ...Orlando Luongo, Hernando Quevedoopenaire +5 more sourcesFIVE-YEAR WILKINSON MICROWAVE ANISOTROPY PROBE OBSERVATIONS: COSMOLOGICAL INTERPRETATION [PDF]
, 2008 The Wilkinson Microwave Anisotropy Probe (WMAP) 5-year data provide stringent limits on deviations from the minimal, six-parameter Λ cold dark matter model. We report these limits and use them to constrain the physics of cosmic inflation via Gaussianity, E. Komatsu, J. Dunkley, J. Dunkley, M. Nolta, C. Bennett, B. Gold, G. Hinshaw, N. Jarosik, D.

International Journal of Modern Physics D, 2009 We present here the transformations required to recast the Robertson–Walker metric and Friedmann–Robertson–Walker equations in terms of observer-dependent coordinates for several commonly assumed cosmologies.
