Searching for non-Gaussianity in the WMAP data
A. Bernui, M. J. Reboucas
Some analyses of recent cosmic microwave background (CMB) data have provided hints that there are deviations from Gaussianity in the WMAP CMB temperature fluctuations. Given the fa…
Energy conditions bounds and their confrontation with supernovae data
M. P. Lima, S. Vitenti, M. J. Reboucas
The energy conditions play an important role in the understanding of several properties of the Universe, including the current accelerating expansion phase and the possible existen…
A note on the large-angle anisotropies in the WMAP cut-sky maps
A. Bernui, B. Mota, M. J. Reboucas +1
Recent analyses of the WMAP data seem to indicate the possible presence of large-angle anisotropy in the Universe. If confirmed, these can have important consequences for our under…
Lookback time bounds from energy conditions
J. Santos, J. S. Alcaniz, M. J. Reboucas +1
In general relativity, the energy conditions are invoked to restrict general energy-momentum tensors on physical grounds. We show that in the standard Friedmann-Lemaitre-Robertson-…
Cosmic Topology: a Brief Overview
M. J. Reboucas, G. I. Gomero
Questions such as whether we live in a spatially finite universe, and what its shape and size may be, are among the fundamental open problems that high precision modern cosmology n…
