We present a nonlinear post-Friedmann framework for structure formation, generalizing to cosmology the weak-field (post-Minkowskian) approximation, unifying the treatment of small and large scales.…
Cosmology with Phase 1 of the Square Kilometre Array Red Book 2018: Technical specifications and performance forecasts
Abstract We present a detailed overview of the cosmological surveys that we aim to carry out with Phase 1 of the Square Kilometre Array (SKA1) and the science that they will enable. We highlight…

The observed galaxy power spectrum acquires relativistic corrections from light-cone effects, and these corrections grow on very large scales. Future galaxy surveys in optical, infrared and radio…
How the scalar field of unified dark matter models can cluster
- D. Bertacca, N. Bartolo, A. Diaferio, S. Matarrese
- Physics, Computer Science
- 7 July 2008
In this framework, a technique for reconstructing models where the effective speed of sound is small enough that the scalar field can cluster is proposed, which avoids the strong time evolution of the gravitational potential and the large integrated Sachs–Wolfe effect.
Characterizing the cosmological gravitational wave background: Anisotropies and non-Gaussianity
