Is the universe finite or infinite, and what shape does it have? These fundamental questions, of which relatively little is known, are typically studied within the context of the standard model of cosmology where the universe is assumed to be homogeneous and isotropic. While these two hypotheses are well-motivated, they are not realistic on all scales of description. Here we address the above questions in highly general cosmological models, with the only assumption being that the average flow… Expand
M ar 2 02 1 Rich Extra Dimensions Are Hidden Inside Black Holes
We present arguments that show why it is difficult to see rich extra dimensions in the Universe. More precisely, we study the conditions under which significant size and variation of the extraExpand
Cosmic cloaking of rich extra dimensions
We present arguments that show why it is difficult to see rich extra dimensions in the universe. Conditions are found where significant size and variation of the extra dimensions in a Kaluza–KleinExpand

How Isotropic is the Universe?
A fundamental assumption in the standard model of cosmology is that the Universe is isotropic on large scales. Breaking this assumption leads to a set of solutions to Einstein's field equations,Expand
Cosmic Topology
TLDR
The main mathematical properties of multi{connected spaces are reviewed, and the tools to classify them and to analyse their properties are described, to search for a possible signature ofmulti{connectedness, or to constrain the models. Expand
CMB anisotropy in compact hyperbolic universes. II. COBE maps and limits
We calculate the CMB anisotropy in compact hyperbolic universe models using the regularized method of images described in paper-I, including the 'line-of-sight `integrated Sachs-Wolfe' effect, asExpand
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
Cosmological models: Cargese lectures 1998
The aim of this set of lectures is a systematic presentation of a 1 + 3 covariant approach to studying the geometry, dynamics, and observational properties of relativistic cosmological models. InExpand
CMB anisotropy in compact hyperbolic universes. I. Computing correlation functions
Cosmic microwave background ~CMB! anisotropy measurements have brought the issue of global topology of the universe from the realm of theoretical possibility to within the grasp of observations. TheExpand
Planck evidence for a closed Universe and a possible crisis for cosmology
The recent Planck Legacy 2018 release has confirmed the presence of an enhanced lensing amplitude in cosmic microwave background power spectra compared with that predicted in the standard Λ cold darkExpand
Spatial density fluctuations and selection effects in galaxy redshift surveys
One of the main problems of observational cosmology is to determine the range in which a reliable measurement of galaxy correlations is possible. This corresponds to determine the shape of theExpand
CMB anisotropy in compact hyperbolic universes
Measurements of CMB anisotropy are ideal experiments for discovering the non-trivial global topology of the universe. To evaluate the CMB anisotropy in multiply-connected compact cosmological models,Expand
Size of the Observable Universe
Because of the expansion of space and the finite age of the cosmos, there exists a horizon beyond which the light emitted by objects will never be able to reach us, marking the bounds of theExpand
