Cosmological Constraints from Multiple Probes in the Dark Energy Survey

Bacon, D.; Bechtol, K.; Challis, P. +161 more

The combination of multiple observational probes has long been advocated as a powerful technique to constrain cosmological parameters, in particular dark energy. The Dark Energy Survey has measured 207 spectroscopically confirmed type Ia supernova light curves, the baryon acoustic oscillation feature, weak gravitational lensing, and galaxy cluster…

Upper Bound of Neutrino Masses from Combined Cosmological Observations and Particle Physics Experiments

Lahav, Ofer; Manera, Marc; Loureiro, Arthur +9 more

We investigate the impact of prior models on the upper bound of the sum of neutrino masses, ∑m_ν . Using data from the large scale structure of galaxies, cosmic microwave background, type Ia supernovae, and big bang nucleosynthesis, we argue that cosmological neutrino mass and hierarchy determination should be pursued using exact models,…
