“…While neutrino parameters may eventually be determined from cosmology [30] or oscillation experiments [31], there is no other way to probe SN neutrino emission or explosion parameters in detail. One needs measurements of the received neutrino fluxes, which, when interpreted with guidance from state-of-the-art SN simulations [10,11], could reveal important aspects of SN physics.…”

Testing coupled dark energy with next-generation large-scale observations

Coupling dark energy to dark matter provides one of the simplest way to effectively modify gravity at large scales without strong constraints from local (i.e. solar system) observations. Models of coupled dark energy have been studied several times in the past and are already significantly constrained by cosmic microwave background experiments. In this paper we estimate the constraints that future large-scale observations will be able to put on the coupling and in general on all the parameters of the model. We combine cosmic microwave background, tomographic weak lensing, redshift distortions and power spectrum probes. We show that next-generation observations can improve the current constraint on the coupling to dark matter by two orders of magnitude; this constraint is complementary to the current solar-system bounds on a coupling to baryons.

The presence of massive neutrinos has a characteristic impact on the growth of large scale structures such as galaxy clusters. We forecast on the capability of the number count and power spectrum measured from the ongoing and future Sunyaev-Zeldovich (SZ) cluster surveys, combined with cosmic microwave background (CMB) observation to constrain the total neutrino mass Mν in a flat ΛCDM cosmology. We adopt self-calibration for the mass-observable scaling relation, and evaluate constraints for the South Pole Telescope normal and with polarization (SPT, SPTPol), Planck, and Atacama Cosmology Telescope Polarization (ACTPol) surveys. We find that a sample of ≈ 1000 clusters obtained from the Planck cluster survey plus extra information from CMB lensing extraction could tighten the current upper bound on the sum of neutrino masses to σM ν = 0.17 eV at 68% C.L. Our analysis shows that cluster number counts and power spectrum provide complementary constraints and as a result they help reducing the error bars on Mν by a factor of 4 − 8 when both probes are combined. We also show that the main strength of cluster measurements in constraining Mν is when good control of cluster systematics is available. When applying a weak prior on the mass-observable relations, which can be at reach in the upcoming cluster surveys, we obtain σM ν = 0.48 eV using cluster only probes and, more interestingly, σM ν = 0.08 eV using cluster + CMB which corresponds to a S/N ≈ 4 detection for Mν ≥ 0.3 eV. We analyze and discuss the degeneracies of Mν with other parameters and investigate the sensitivity of neutrino mass constraints with various surveys specifications.
