A test of the Poincaré dodecahedral space topology hypothesis with the WMAP CMB data

  journal={Astronomy and Astrophysics},
It has been suggested by Roukema and coworkers (hereafter R04) that the topology of the Universe as probed by the “matched circles” method using the first year release of the WMAP CMB data, might be that of the Poincare dodecahedral space (PDS) model. An excess in the correlation of the “identified circles” was reported by R04, for circles of angular radius of ~11° for a relative phase twist -36°, hinting that this could be due to a Clifford translation, if the hypothesized model were true. R04…

Poincaré dodecahedral space parameter estimates

Context. Several studies have proposed that the preferred model of the comoving spatial 3-hypersurface of the Universe may be a Poincare dodecahedral space (PDS) rather than a simply connected,

The optimal phase of the generalised Poincaré dodecahedral space hypothesis implied by the spatial cross-correlation function of the WMAP sky maps

Context. Small universe models predicted a cutoff in large-scale power in the cosmic microwave background (CMB). This was detected by the Wilkinson Microwave Anisotropy Probe (WMAP). Several studies

The topology and size of the universe from CMB temperature and polarization data

We analyze seven year and nine year WMAP temperature maps for signatures of three finite flat topologies 0 = 3, 1 = 2 × 1, and 2 = S1 × 2. We use Monte-Carlo simulations with the Feldman-Cousins

The residual gravity acceleration effect in the Poincaré dodecahedral space

Context. In a flat space, it has been shown heuristically that the global topology of comoving space can affect the dynamics expected in the weak-field Newtonian limit, inducing a weak acceleration

The Status of Cosmic Topology after Planck Data

In the last decade, the study of the overall shape of the universe, called Cosmic Topology, has become testable by astronomical observations, especially the data from the Cosmic Microwave Background

The study of topology of the Universe using multipole vectors

We study a multipole vector-based decomposition of cosmic microwave background data in order to search for signatures of a multiconnected topology of the universe. Using 10 6 simulated maps, we

Planck 2015 results. XVIII. Background geometry & topology

Full-sky CMB maps from the 2015 Planck release allow us to detect departures from global isotropy on the largest scales. We present the first searches using CMB polarization for correlations induced

A spatial correlation analysis for a toroidal universe

The spatial cross-correlation function ξC recently introduced by Roukema et al (2008 Astron. Astrophys. 486 55 (arXiv:0801.0006 [astro-ph])) is applied to the equilateral toroidal topology of the

An improved cosmic crystallography method to detect holonomies in flat spaces

A new, improved version of a cosmic crystallography method for constraining cosmic topology is introduced. Like the circles-inthe-sky method using CMB data, we work in a thin, shell-like region

On the possibility of constraining cosmic topology from the celestial distribution of astronomical objects

We present a method to constrain cosmic topology from the distribution of astronomical objects projected on the celestial sphere. This is an extension of the 3D method introduced in Fujii & Yoshii



A new analysis of the Poincar dodecahedral space model

Context. The full three-year Wilkinson Microwave Anisotropy Probe results (hereafter WMAP3) reinforce the absence of large-angle correlations at scales greater than 60 ◦ . The Poincare dodecahedral

Constraints on the topology of the universe from the 2-year COBE data

The cosmic microwave background (CMB) is a unique probe of cosmological parameters and conditions. There is a connection between anisotropy in the CMB and the topology of the Universe. Adopting a

A hint of Poincaré dodecahedral topology in the WMAP first year sky map

Several analyses of the cosmic microwave background map made by the satellite WMAP suggest that the global shape of a spatial section of the Universe is that of a Poincare dodecahedral space. A

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.

Constraining topology in harmonic space

We consider several ways to test for topology directly in harmonic space by comparing the measured a[script-l]m with the expected correlation matrices. Two tests are of a frequentist nature while we

Cosmic Crystallography

The topology of the Universe can leave an imprint on the cosmic microwave background (CMB) radiation. Clues to the shape of our Universe can be found by searching the CMB for matching circles of
