On cosmological observables in a swiss-cheese universe
Valerio Marra, Edward W. Kolb, Sabino Matarrese +1
Photon geodesics are calculated in a swiss-cheese model, where the cheese is made of the usual Friedmann-Robertson-Walker solution and the holes are constructed from a Lemaitre-Tol…
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…
On Resonant Leptogenesis
Andrea De Simone, Antonio Riotto
It has been recently shown that the quantum Boltzmann equations may be relevant for the leptogenesis scenario. In particular, they lead to a time-dependent CP asymmetry which depen…
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…
Quantum Boltzmann Equations and Leptogenesis
Andrea De Simone, Antonio Riotto
The closed time-path formalism is a powerful Green's function formulation to describe non-equilibrium phenomena in field theory and it leads to a complete non-equilibrium quantum k…
