What galaxy surveys really measure
In this paper we compute the quantity which is truly measured in a large galaxy survey. We take into account the effects coming from the fact that we actually observe galaxy redshifts and skyExpand
Fluctuations of the luminosity distance
We derive an expression for the luminosity distance in a perturbed Friedmann universe. We define the correlation function and the power spectrum of the luminosity distance fluctuations and expressExpand
Cosmology and fundamental physics with the Euclid satellite
This review is meant to provide a guide to the scientific themes that will underlie the activity of the group during the preparation of the Euclid mission and discusses five broad topics: dark energy and modified gravity, dark matter, initial conditions, basic assumptions and questions of methodology in the data analysis.

The CLASSgal code for relativistic cosmological large scale structure
We present accurate and efficient computations of large scale structure observables, obtained with a modified version of the c l ass code which is made publicly available. This code includes allExpand
Cosmological magnetic fields: their generation, evolution and observation
We review the possible mechanisms for the generation of cosmological magnetic fields, discuss their evolution in an expanding Universe filled with the cosmic plasma and provide a critical review ofExpand
Cosmological perturbation theory
This is a review on cosmological perturbation theory. After an introduction, it presents the problem of gauge transformation. Gauge invariant variables are introduced and the Einstein andExpand
The stochastic gravitational wave background from turbulence and magnetic fields generated by a first-order phase transition
We analytically derive the spectrum of gravitational waves due to magneto-hydrodynamical turbulence generated by bubble collisions in a first-order phase transition. In contrast to previous studies,Expand
Dipole of the luminosity distance: a direct measure of H(z).
It is shown that the dipole of the luminosity distance is a useful observational tool which allows us to determine the Hubble parameter as a function of redshift H(z) and to distinguish between different models for dark energy. Expand
Cosmological ensemble and directional averages of observables
We show that at second order, ensemble averages of observables and directional averages do not commute due to gravitational lensing -- observing the same thing in many directions over the sky is notExpand
