Dynamical suppression of non-adiabatic modes
Massimo Giovannini
Recent analyses of the WMAP 5-year data constrain possible non-adiabatic contributions to the initial conditions of CMB anisotropies. Depending upon the early dynamics of the plasm…
Faraday rotation, stochastic magnetic fields and CMB maps
Massimo Giovannini, Kerstin E. Kunze
The high- and low-frequency descriptions of the pre-decoupling plasma are deduced from the Vlasov-Landau treatment generalized to curved space-times and in the presence of the rela…
CMB polarization induced by stochastic magnetic fields
Massimo Giovannini, Kerstin E. Kunze
The complete calculation of the CMB polarization observables (i.e. E- and B-modes) is reported within the conventional CDM paradigm supplemented by a stochastic magnetic field.…
Generalized CMB initial conditions with pre-equality magnetic fields
Massimo Giovannini, Kerstin E. Kunze
The most general initial conditions of CMB anisotropies, compatible with the presence of pre-equality magnetic fields, are derived. When the plasma is composed by photons, baryons,…
Large-scale magnetic fields, curvature fluctuations and the thermal history of the Universe
Massimo Giovannini
It is shown that gravitating magnetic fields affect the evolution of curvature perturbations in a way that is reminiscent of a pristine non-adiabatic pressure fluctuation. The gaug…
Semi-analytical approach to magnetized temperature autocorrelations
Massimo Giovannini
The cosmic microwave background (CMB) temperature autocorrelations, induced by a magnetized adiabatic mode of curvature inhomogeneities, are computed with semi-analytical methods.…
