The Shape and Topology of the Universe
Jean-Pierre Luminet
What is the shape of the Universe? Is it curved or flat, finite or infinite ? Is space "wrapped around" to create ghost images of faraway cosmic sources? We review how tessellation…
Shock waves in tidally compressed stars by massive black holes
M. Brassart, J. -P. Luminet
We interest in the case of a main-sequence star deeply penetrating within the tidal radius of a massive black hole. We focus on the compression phase leading to a so-called pancake…
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…
The Rise of Big Bang Models, from Myth to Theory and Observations
Jean-Pierre Luminet
We provide an epistemological analysis of the developments of relativistic cosmology from 1917 to 2006, based on the seminal articles by Einstein, de Sitter, Friedmann, Lemaitre, H…
Geometry and Topology in Relativistic Cosmology
Jean-Pierre Luminet
General relativity does not allow one to specify the topology of space, leaving the possibility that space is multiply rather than simply connected. We review the main mathematical…
Constraining Cosmic Topology with CMB Polarization
Alain Riazuelo, Samuel Caillerie, Marc Lachièze-Rey +2
Multiply connected space sections of the universe on a scale smaller than the horizon size can leave an imprint on cosmic microwave background polarization maps, in such a way that…
