Future constraints on neutrino isocurvature perturbations in the curvaton scenario
Eleonora Di Valentino, Massimiliano Lattanzi, Gianpiero Mangano +2
In the curvaton scenario, residual isocurvature perturbations can be imprinted in the cosmic neutrino component after the decay of the curvaton field, implying in turn a non-zero c…
Updated BBN bounds on the cosmological lepton asymmetry for non-zero theta13
Gianpiero Mangano, Gennaro Miele, Sergio Pastor +2
We discuss the bounds on the cosmological lepton number from Big Bang Nucleosynthesis (BBN), in light of recent evidences for a large value of the neutrino mixing angle theta13. Th…
Coarse-Grained Cosmological Perturbation Theory
Massimo Pietroni, Gianpiero Mangano, Ninetta Saviano +1
Semi-analytical methods, based on Eulerian perturbation theory, are a promising tool to follow the time evolution of cosmological perturbations at small redshifts and at mildly non…
A robust upper limit on N_eff from BBN, circa 2011
Gianpiero Mangano, Pasquale D. Serpico
We derive here a robust bound on the effective number of neutrinos from constraints on primordial nucleosynthesis yields of deuterium and helium. In particular, our results are bas…
