Circles-in-the-sky searches and observable cosmic topology in the inflationary limit
B. Mota, M. J. Reboucas, R. Tavakol
While the topology of the Universe is at present not specified by any known fundamental theory, it may in principle be determined through observations. In particular, a non-trivial…
Mapping the large-scale anisotropy in the WMAP data
A. Bernui, B. Mota, M. J. Reboucas +1
Analyses of recent cosmic microwave background (CMB) observations have provided increasing indications for the existence of large scale anisotropy in the universe. Given the far re…
Supernovae observations and cosmic topology
M. J. Reboucas, J. S. Alcaniz, B. Mota +1
Two fundamental questions regarding our description of the Universe concern the geometry and topology of its 3-dimensional space. While geometry is a local characteristic that give…
Constraints from the Detection of Cosmic Topology on the Generalized Chaplygin Gas
M. Makler, B. Mota, M. J. Reboucas
Despite our present-day inability to predict the topology of the universe one may expect that we should be able to detect it in the near future, given the increasing accuracy in th…
Detectability of Cosmic Topology in Generalized Chaplygin Gas Models
B. Mota, M. Makler, M. J. Reboucas
If the spatial section of the universe is multiply connected, repeated images or patterns are expected to be detected observationally. However, due to the finite distance to the la…
The Local Shape of the Universe in the Inflationary Limit
B. Mota, M. J. Reboucas, R. Tavakol
Recent high precision data by WMAP and SDSS have provided strong evidence to suggest that the universe is nearly flat. They are also making it possible to probe the topology of the…
