The last years have been an exciting period for the field of the Cosmic Microwave Background (CMB) research. With recent CMB balloon-borne and ground-based experiments we are entering a new era of 'precision' cosmology that enables us to use the CMB anisotropy measurements to constrain the cosmological parameters and test new theoretical scenarios.

Polarization of the Microwave Background: theoretical framework
We present a brief review of the polarization properties of the cosmic microwave background in dark matter models for structure formation. Quite independently of the model parameters, theExpand
Cosmological Constraints from Current Cosmic Microwave Background and Type Ia Supernova Data: A Brute Force, Eight-Parameter Analysis
We describe constraints on a "standard" eight-parameter, open cold dark matter (CDM) model from the most recent cosmic microwave background and Type Ia supernova data. Our parameters are theExpand
Cosmic Microwave Background anisotropies beyond the third peak
Forthcoming Cosmic Microwave Background (CMB) experiments will allow us to accurately investigate the power spectrum at very small scales ('>1000). We predict the level of the primary anisotropies,Expand
The physics of microwave background anisotropies
The residual radiation from the Big Bang is observable as the cosmic microwave background–a near-uniform sea of photons with an average temperature of 2.7 K. Small variations in the temperature ofExpand

TLDR
A likelihood analysis of the recent data on the cosmic microwave background radiation anisotropy from the BOOMERANG experiment places a strong upper bound on the radiation density present at recombination, and yields a firm upper limit on the lepton asymmetry in the Universe. Expand
New constraints on inflation from the cosmic microwave background
The recent data from the BOOMERANG and MAXIMA-1 balloon flights have marked the beginning of the precision era of cosmic microwave background (CMB) anisotropy measurements. We investigate theExpand
Correlated perturbations from inflation and the cosmic microwave background.
TLDR
It is found that there is a degeneracy between the amplitude of correlated isocurvature perturbations and the spectral tilt, and estimates of the baryon and CDM densities are found to be almost independent of the isocURvature amplitude. Expand
Early universe constraints on a time varying fine structure constant
Higher-dimensional theories have the remarkable feature of predicting a time (and hence redshift) dependence of the `fundamental' four dimensional constants on cosmological timescales. In this paperExpand

The bulk of the hydrogen in the universe transformed from neutral to ionized somewhere in the redshift interval 5 < z < 40, most likely due to ionizing photons produced by an early generation ofExpand
A measurement by BOOMERANG of multiple peaks in the angular power spectrum of the cosmic microwave background
