AdS - de Sitter transition in interacting dark energy models
Yifei Zhao, Jailson Alcaniz, Humberto A. Borges +2
Recent cosmological results, including the persistent tension and indications of dynamical dark energy, have raised the possibility that the standard -Cold Dark Matter ($Λ…
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…
ACT DR6+Planck impact on inflation with non-zero vacuum expectation value and the post-inflationary behavior
F. B. M. dos Santos, J. G. Rodrigues, G. Rodrigues +2
The impact of the most recent cosmic microwave background (CMB) data from the Atacama Cosmology Telescope (ACT) is studied for a model of cosmic inflation which predicts a non-zero…
Dark energy and cosmic acceleration
Rodrigo von Marttens, Jailson Alcaniz
The discovery that we live in an accelerating universe changed drastically the paradigm of physics and introduced the concept of \textit{dark energy}. In this work, we present a br…
Dark Matter Freeze-In during Warm Inflation and the Seesaw Mechanism
Rayff de Souza, Jamerson G. Rodrigues, Clarissa Siqueira +2
A compelling way to address the inflationary period is via the warm inflation scenario, where the interaction of the inflaton field with other degrees of freedom affects its dynami…
Assessing the dark degeneracy through the gas mass fraction data
Dinorah Barbosa, Rodrigo von Marttens, Javier Gonzalez +1
It is well-known that Einstein's equations constrain only the total energy-momentum tensor of the cosmic substratum, without specifying the characteristics of its individual consti…
