Seeing Relativity -- III. Journeying within the Kerr metric toward the negative gravity region
Alain Riazuelo
In this paper we study some features of the Kerr metric both from an analytic and a visual point of view by performing accurate raytracing in various situations. We focus on featur…
Seeing relativity -- II. Revisiting and visualizing the Reissner-Nordström metric
Alain Riazuelo
In this paper we study some features of the Reissner-Nordström metric both from an analytic and a visual point of view. We perform an accurate ray tracing and study of null geodesi…
Seeing relativity -- I. Ray tracing in a Schwarzschild metric to explore the maximal analytic extension of the metric and making a proper rendering of the stars
Alain Riazuelo
We present an implementation of a ray tracing code in the Schwarzschild metric. We aim at building a numerical code with a correct implementation of both special (aberration, ampli…
Planck 2013 results. XXVI. Background geometry and topology of the Universe
Planck Collaboration, P. A. R. Ade, N. Aghanim +223
Planck CMB temperature maps allow detection of large-scale departures from homogeneity and isotropy. We search for topology with a fundamental domain nearly intersecting the last s…
The study of topology of the universe using multipole vectors
P. Bielewicz, A. Riazuelo
We study a multipole vector-based decomposition of cosmic microwave background (CMB) data in order to search for signatures of a multiconnected topology of the universe. Using 10^6…
A new analysis of Poincaré dodecahedral space model
S. Caillerie, M. Lachièze-Rey, J. -P. Luminet +3
The full three-year WMAP results (WMAP3) reinforce the absence of large-angle correlations at scales greater than 60 degrees. The Poincare dodecahedral space (PDS) model model, whi…
