A magnetized completion of the CDM paradigm
Massimo Giovannini, Kerstin E. Kunze
The standard CDM paradigm is complemented with a magnetized contribution whose effects on the anisotropies of the Cosmic Microwave Background (CMB) are assessed by means of a de…
Time-dependent gravitating solitons in five dimensional warped space-times
Massimo Giovannini
Time-dependent soliton solutions are explicitly derived in a five-dimensional theory endowed with one (warped) extra-dimension. Some of the obtained geometries, everywhere well def…
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.…
Why CMB physics?
Massimo Giovannini
The aim of these lectures is to introduce some basic problems arising in gravitation and modern cosmology. All along the discussion the guiding theme is provided by the phenomenolo…
Testing PVLAS axions with resonant photon splitting
Emidio Gabrielli, Massimo Giovannini
The photon splitting gamma -> gamma gamma in a time-independent and inhomogeneous magnetized background is considered when neutral and ultralight spin-0 particles are coupled to tw…
