We measure the skewness power spectrum of the Cosmic Microwave Background (CMB) anisotropies optimized for a detection of the secondary bispectrum generated by the correlation of the CMB lensing...
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...
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...
Cosmic Microwave Weak lensing data as a test for the dark universe (2008)
Calabrese, Erminia, Slosar, Anze, Melchiorri, Alessandro, Smoot, George F., Zahn, Oliver
Combined analyses of WMAP 3-year and ACBAR Cosmic Microwave Anisotropies angular power spectra have presented evidence for gravitational lensing >3 sigma level. This signal could provide a relevant...
