An improved limit on the neutrino mass with CMB and redshift-dependent halo bias-mass relations from SDSS, DEEP2, and Lyman-Break Galaxies
Francesco De Bernardis, Paolo Serra, Asantha Cooray +1
We use measurements of luminosity-dependent galaxy bias at several different redshifts, SDSS at , DEEP2 at and LBGs at , combined with WMAP five-year cosmic mi…
Impact of Point Source Clustering on Cosmological Parameters with CMB Anisotropies
Paolo Serra, Asantha Cooray, Alexandre Amblard +2
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 dis…
Observables sensitive to absolute neutrino masses. II
G. L. Fogli, E. Lisi, A. Marrone +6
In this followup to Phys. Rev. D 75, 053001 (2007) [arXiv:hep-ph/0608060] we report updated constraints on neutrino mass-mixing parameters, in light of recent neutrino oscillation…
Anisotropies in the Cosmic Neutrino Background after WMAP 5-year Data
Francesco De Bernardis, Luca Pagano, Paolo Serra +2
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 ba…
Weak Lensing of the Primary CMB Bispectrum
Asantha Cooray, Devdeep Sarkar, Paolo Serra
The cosmic microwave background (CMB) bispectrum is a well-known probe of the non-Gaussianity of primordial perturbations. Just as the intervening large-scale structure modifies th…
Cosmic Shear from Scalar-Induced Gravitational Waves
Devdeep Sarkar, Paolo Serra, Asantha Cooray +2
Weak gravitational lensing by foreground density perturbations generates a gradient mode in the shear of background images. In contrast, cosmological tensor perturbations induce a…
