PublicaciónForeground Contributions to 0.2-2° CMB Anisotropies
We examine the extent to which galactic and extragalactic foregrounds can hamper the detection of primordial Cosmic Microwave background (CMB) anisotropies. We...

PublicaciónImproved CMB anisotropy constraints on primordial magnetic fields from the post-recombination ionization history
We investigate the impact of a stochastic background of primordial magnetic fields (PMF) generated before recombination on the ionization history of the...
