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…
A comparative analysis of dissipation coefficients in warm inflation
F. B. M. dos Santos, R. de Souza, J. S. Alcaniz
In the warm inflation scenario, the early cosmic acceleration is driven by the inflaton coupled to thermal fields, decaying into radiation and leaving a hot universe populated by r…
Is natural inflation in agreement with CMB data?
F. B. M. dos Santos, G. Rodrigues, J. G. Rodrigues +2
Natural inflation is a well-motivated model for the early universe in which an inflaton potential of the pseudo-Nambu-Goldstone form, , can naturally d…
Constraints on the non-minimally coupled Witten-O'Raifeartaigh inflation
F. B. M. dos Santos, R. Silva, J. S. Alcaniz
We investigate the impact of a non-minimal coupling of the scalar field with gravity in inflationary models, where a small coupling is allowed. As a concrete example, we consider t…
Updating constraints on phantom crossing gravity
F. B. M. dos Santos
We establish constraints on gravity by considering the possibility of a scenario that supports a phantom crossing of the equation of state parameter . After determin…
Warm -exponential inflation and the Swampland Conjectures
F. B. M. dos Santos, R. Silva, S. Santos da Costa +2
We investigate theoretical and observational aspects of a warm inflation scenario driven by the -exponential potential, which generalizes the well-known power law inflation. In…
Revisiting Witten-O'Raifeartaigh Inflation for a Non-minimally Coupled Scalar Field
F. B. M. dos Santos, R. Silva
In this work, we revisit the Witten-O'Raifeartaigh model of inflation, in which the potential takes a form, when the scalar field is non-minimally coupl…
Observational Constraints on Gravity from Model-Independent Data
F. B. M. dos Santos, J. E. Gonzalez, R. Silva
We establish new constraints on gravity models by using cosmological data. In particular, we investigate the restrictions given by the gas mass fraction measurements of gala…
Constraining non-minimally coupled -exponential inflation with CMB data
Felipe Bruno Medeiros dos Santos, Simony Santos da Costa, Raimundo Silva +2
The -exponential inflation is driven by a class of primordial potentials, derived in the framework of braneworld scenarios, that generalizes the well-known power law inflation.…
