Description of our cosmological spacetime as a perturbed conformal Newtonian metric and implications for the backreaction proposal for the accelerating universe
Edward W. Kolb, Valerio Marra, Sabino Matarrese
It has been argued that the spacetime of our universe can be accurately described by a perturbed conformal Newtonian metric, and hence even large density inhomogeneities in a dust…
Full-sky maps for gravitational lensing of the CMB
Carmelita Carbone, Volker Springel, Carlo Baccigalupi +2
We use the large cosmological Millennium Simulation (MS) to construct the first all-sky maps of the lensing potential and the deflection angle, aiming at gravitational lensing of t…
Light-cone averages in a swiss-cheese universe
Valerio Marra, Edward W. Kolb, Sabino Matarrese
We analyze a toy swiss-cheese cosmological model to study the averaging problem. In our model, the cheese is the EdS model and the holes are constructed from a LTB solution. We stu…
CMB temperature anisotropies from third order gravitational perturbations
G. D'Amico, N. Bartolo, S. Matarrese +1
In this paper we present a complete computation of the Cosmic Microwave Background (CMB) anisotropies up to third order from gravitational perturbations accounting for scalar, vect…
Cosmic Microwave Background Anisotropies up to Second Order
Nicola Bartolo, Sabino Matarrese, Antonio Riotto
These lecture notes present the computation of the full system of Boltzmann equations describing the evolution of the photon, baryon and cold dark matter fluids up to second order…
B-mode polarization of the CMB from the second-order photon quadrupole
Nicola Bartolo, Sabino Matarrese, Silvia Mollerach +1
We study a new contribution to the polarization of the Cosmic Microwave Background induced at the epoch of recombination by the second-order quadrupole moment of the photon distrib…
