Context. 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 gives the intrinsic curvature, topology is a global feature that characterizes the shape and size of the 3-space. The geometry constrains, but does not dictate, the spatial topology. Aims. We show that besides determining the spatial geometry, the knowledge of the spatial topology allows us to place tight… Expand

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, aExpand
Circles-in-the-sky searches and observable cosmic topology in the inflationary limit
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 nontrivial topology willExpand
A relativistic model of the topological acceleration effect
It has previously been shown heuristically that the topology of the Universe affects gravity, in the sense that a test particle near a massive object in a multiply connected universe is subject to aExpand
Pre-inflationary spacetime in string cosmology
Abstract Seiberg and Witten have shown that the non-perturbative stability of string physics on conformally compactified spacetimes is related to the behaviour of the areas and volumes of certainExpand


Cosmic topology: a brief overview
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 needs to resolve.Expand
A theoretician's analysis of the supernova data and the limitations in determining the nature of dark energy
Current cosmological observations show a strong signature of the existence of a dark energy component with negative pressure. The most obvious candidate for this dark energy is the cosmologicalExpand
Dodecahedral space topology as an explanation for weak wide-angle temperature correlations in the cosmic microwave background
A simple geometrical model of a finite space—the Poincaré dodecahedral space—which accounts for WMAP's observations with no fine-tuning required is presented, and the model also predicts temperature correlations in matching circles on the sky. Expand
CMB anisotropy of spherical spaces
The first-year WMAP data taken at their face value hint that the Universe might be slightly positively curved and therefore necessarily finite since all spherical (Clifford?Klein) space forms , givenExpand
Detectability of cosmic topology in almost flat universes
Recent observations suggest that the ratio of the total density to the critical density of the universe, 0, is likely to be very close to one, with a significant proportion of this energy being inExpand
Cosmic acceleration in brane cosmology
Cosmic acceleration may be the result of unknown physical processes involving either new fields in high energy physics or modifications of gravitation theory. In the latter case, such modificationsExpand
Cosmological Parameters from Eigenmode Analysis of Sloan Digital Sky Survey Galaxy Redshifts
We present estimates of cosmological parameters from the application of the Karhunen-Loeve transform to the analysis of the three-dimensional power spectrum of density fluctuations using SloanExpand
Detecting topology in a nearly flat spherical universe
When the density parameter is close to unity, the universe has a large curvature radius independent of its being hyperbolic or spherical, or in the limiting case of an infinite curvature radius,Expand
Constraining the topology of the universe.
The first year data from the Wilkinson Microwave Anisotropy Probe are used to place stringent constraints on the topology of the Universe, and the nondetection rules out the possibility that the authors live in a universe with topology scale smaller than 24 Gpc. Expand
Cosmological parameters from SDSS and WMAP
We measure cosmological parameters using the three-dimensional power spectrum P(k) from over 200,000 galaxies in the Sloan Digital Sky Survey (SDSS) in combination with WMAP and other data. OurExpand
