Determining the Neutrino Mass Hierarchy with Cosmology (2009)
De Bernardis, Francesco, Kitching, Thomas D., Heavens, Alan, Melchiorri, Alessandro
The combination of current large scale structure and cosmic microwave background (CMB) anisotropies data can place strong constraints on the sum of the neutrino masses. Here we show that future...
Observing the Evolution of the Universe (2009)
Aguirre, James, Amblard, Alexandre, Ashoorioon, Amjad, Baccigalupi, Carlo, Balbi, Amedeo, Bartlett, James, ...
How did the universe evolve? The fine angular scale (l>1000) temperature and polarization anisotropies in the CMB are a Rosetta stone for understanding the evolution of the universe. Through detailed...
Delayed Recombination and Standard Rulers (2008)
De Bernardis, Francesco, Bean, Rachel, Galli, Silvia, Melchiorri, Alessandro, Silk, Joseph, Verde, Licia
Measurements of Baryonic Acoustic Oscillations in galaxy surveys have been recognized as a powerful tool for constraining dark energy. However, this method relies on the knowledge of the size of the...
CMBPol Mission Concept Study: Probing Inflation with CMB Polarization (2008)
Baumann, Daniel, Jackson, Mark G, Adshead, Peter, Amblard, Alexandre, Ashoorioon, Amjad, Bartolo, Nicola, ...
We summarize the utility of precise cosmic microwave background (CMB) polarization measurements as probes of the physics of inflation. We focus on the prospects for using CMB measurements to...

De Bernardis, Francesco, Serra, Paolo, Cooray, Asantha, Melchiorri, Alessandro
We use measurements of luminosity-dependent galaxy bias at several different redshifts, SDSS at $z=0.05$, DEEP2 at $z=1$ and LBGs at $z=3.8$, combined with WMAP five-year cosmic microwave background...
Anisotropies in the Cosmic Neutrino Background after WMAP 5-year Data (2008)
De Bernardis, Francesco, Pagano, Luca, Serra, Paolo, Melchiorri, Alessandro, Cooray, Asantha
We search for the presence of cosmological neutrino background (CNB) anisotropies in recent WMAP 5-year data using their signature imprinted on modifications to cosmic microwave background (CMB)...
The Cosmic Neutrino Background and the Age of the Universe (2007)
De Bernardis, Francesco, Melchiorri, Alessandro, Verde, Licia, Jimenez, Raul
We discuss the cosmological degeneracy between the age of the Universe, the Hubble parameter and the effective number of relativistic particles N_eff. We show that independent determinations of the...
De Bernardis, Francesco, Giusarma, Elena, Melchiorri, Alessandro
We demonstrate that the recent measurements of the angular diameter distance of 38 cluster of galaxies using Chandra X-ray data and radio observations from the OVRO and BIMA interferometric arrays...
