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 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…
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…
Thawing quintessence and transient cosmic acceleration in light of DESI
Rayff de Souza, Gabriel Rodrigues, Jailson Alcaniz
Recent analysis of the DESI Collaboration challenges the -Cold Dark Matter (CDM) model, suggesting evidence for a dynamic dark energy. These results are obtained in the con…
Cosmography with DESI DR2 and SN data
Gabriel Rodrigues, Rayff de Souza, Jailson Alcaniz
In this paper, we present a kinematic analysis of the Universe's expansion history using cosmography, with a particular emphasis on the jerk parameter , which is equal to one…
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…
