Supernovae Constraints on DGP Model and Cosmic Topology
@article{Rebouas2007SupernovaeCO, title={Supernovae Constraints on DGP Model and Cosmic Topology}, author={M J Rebouças}, journal={arXiv: Astrophysics}, year={2007} }
We study the constraints that the detection of a non-trivial spatial topology may place on the parameters of braneworld models by considering the Dvali-Gabadadze-Porrati (DGP) and the globally homogeneous Poincar\'e dodecahedral spatial (PDS) topology as a circles-in-the-sky observable topology. To this end we reanalyze the type Ia supernovae constraints on the parameters of the DGP model and show that PDS topology gives rise to strong and complementary constraints on the parameters of the DGP…

A non-trivial spatial topology of the Universe is a potentially observable attribute, which can be probed through the circles-in-the-sky for all locally homogeneous and isotropic universes with no…

The immediate observational consequence of a non-trivial spatial topology of the Universe is that an observer could potentially detect multiple images of radiating sources. In particular, a…
A note on the large-angle anisotropies in the WMAP cut-sky maps

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 understanding of the…
Cosmological constraints on the DGP braneworld model with gamma-ray bursts

We investigate observational constraints on the Dvali, Gabadadze and Porrati (DGP) model with Gamma-ray bursts (GRBs) at high redshift obtained directly from the Union2 Type Ia supernovae data set.…
Constraints on dark energy equation of state parameters from cosmic topology

Despite our present-day inability to predict the topology of the universe it is expected that we should be able to detect it in the near future. A nontrivial detectable topology of the space section…
