Effective Neutrino Mass and Apparent Phantom Crossing
Gabriel Rodrigues, Jamerson Rodrigues, Simony Santos da Costa +1
Recent cosmological constraints on the sum of neutrino masses have reached, and in some analyses fallen below, the minimum value implied by the normal mass ordering, suggesting a p…
Cosmological Constraints on Neutrino Masses in Quintessential Inflation
Jamerson Rodrigues, Gabriel Rodrigues, Felipe B. M. dos Santos +2
Quintessential inflation provides a unified description of the early and late accelerated phases of the Universe, linking the inflationary epoch to the present-day dark energy-domi…
J-PAS: Forecasting constraints on Neutrino Masses
Gabriel Rodrigues, Antonio J. Cuesta, Jailson Alcaniz +30
The large-scale structure survey J-PAS is taking data since October 2023. In this work, we present a forecast based on the Fisher matrix method to establish its sensitivity to the…
J-PAS and PFS surveys in the era of dark energy and neutrino mass measurements
Fuxing Qin, Yuting Wang, Gong-Bo Zhao +28
Fisher-matrix forecasts are presented for the cosmological surveys of the Javalambre Physics of the Accelerating Universe Astrophysical Survey (J-PAS) and the Subaru Prime Focus Sp…
Thawing Dark Energy and Massive Neutrinos in Light of DESI
Gabriel Rodrigues, Rayff de Souza, Jamerson Rodrigues +1
Recent analyses have shown that a dynamic dark energy modeled by the CPL parameterization of the dark energy equation of state (EoS) can ease constraints on the total neutrino mass…
