Cosmological constraints from Microwave Background Anisotropy and Polarization
Alessandro Melchiorri
The recent high-quality measurements of the Cosmic Microwave Background anisotropies have presented cosmologists with the possibility of studying the large scale properties of our…
Maps of the millimetre sky from the BOOMERanG experiment
P. de Bernardis, P. A. R. Ade, A. Balbi +38
In the 1998-99 flight, BOOMERanG has produced maps of of the sky at high Galactic latitudes, at frequencies of 90, 150, 240 and 410 GHz, with resolution $\simgt 10'$. Th…
Measuring in the Early Universe: CMB Polarization, Reionization and the Fisher Matrix Analysis
G. Rocha, R. Trotta, C. J. A. P. Martins +4
We present a detailed analysis of present and future Cosmic Microwave Background constraints of the value of the fine-structure constant, . We carry out a more detailed analysis…
New constraints on varying
G. Rocha, R. Trotta, C. J. A. P. Martins +3
We present a summary of recent constraints on the value of the fine-structure constant at the epoch of decoupling from the recent observations made by the Wilkinson Microwave Aniso…
Recombining WMAP: constraints on ionizing and resonance radiation at recombination
Rachel Bean, Alessandro Melchiorri, Joe Silk
We place new constraints on sources of ionizing and resonance radiation at the epoch of the recombination process using the recent CMB temperature and polarization spectra coming f…
WMAPping inflationary physics
William H. Kinney, Edward W. Kolb, Alessandro Melchiorri +1
We extract parameters relevant for distinguishing among single-field inflation models from the Wilkinson Microwave Anisotropy Probe (WMAP) data set, and from a combination of the W…
