CMB Lensing Constraints on Dark Energy and Modified Gravity Scenarios (2009)
Calabrese, Erminia, Cooray, Asantha, Martinelli, Matteo, Melchiorri, Alessandro, Pagano, Luca, Slosar, Anze, ...
Weak gravitational lensing leaves a characteristic imprint on the cosmic microwave background temperature and polarization angular power spectra. Here we investigate the possible constraints on the...
Pagano, Luca, De Bernardis, Paolo, De Troia, Grazia, Gubitosi, Giulia, Masi, Silvia, Melchiorri, Alessandro, ...
Cosmic Microwave Background experiments must achieve very accurate calibration of their polarization reference frame to avoid biasing the cosmological parameters. In particular, a wrong or inaccurate...
A Constraint on Planck-scale Modifications to Electrodynamics with CMB polarization data (2009)
Gubitosi, Giulia, Pagano, Luca, Amelino-Camelia, Giovanni, Melchiorri, Alessandro, Cooray, Asantha
We show that the Cosmic Microwave Background (CMB) polarization data gathered by the BOOMERanG 2003 flight and WMAP provide an opportunity to investigate {\it in-vacuo} birefringence, of a type...
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...
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...

Impact of Point Source Clustering on Cosmological Parameters with CMB Anisotropies (2008)
Serra, Paolo, Cooray, Asantha, Amblard, Alexandre, Pagano, Luca, Melchiorri, Alessandro
The faint radio point sources that are unresolved in cosmic microwave background (CMB) anisotropy maps are likely to be a biased tracer of the large-scale structure dark matter distribution. While...
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)...
Red density perturbations and inflationary gravitational waves (2008)
Pagano, Luca, Cooray, Asantha, Melchiorri, Alessandro, Kamionkowski, Marc
We study the implications of recent indications from the Wilkinson Microwave Anisotropy Probe (WMAP) and other cosmological data for a red spectrum of primordial density perturbations for the...
Red Density Perturbations and Inflationary Gravitational Waves (2007)
Pagano, Luca, Cooray, Asantha, Melchiorri, Alessandro, Kamionkowski, Marc
We study the implications of recent indications for a red spectrum of primordial density perturbations for the detection of inflationary gravitational waves (IGWs) with forthcoming cosmic microwave...

When Did Cosmic Acceleration Start ? (2007)
Melchiorri, Alessandro, Pagano, Luca, Pandolfi, Stefania
A precise determination, and comparison, of the epoch of the onset of cosmic acceleration, at redshift z_acc, and of dark energy domination, at z_eq, provides an interesting measure with which to...
