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…
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…
Testing the isotropy of cosmic acceleration with Pantheon+ and SH0ES: A cosmographic analysis
Carlos A. P. Bengaly, Cássio Pigozzo, Jailson S. Alcaniz
We use a recent Pantheon+SH0ES compilation of Type Ia Supernova distance measurements at low-redshift, i.e., , in order to investigate the directional depend…
Cosmology and fundamental physics with the ELT-ANDES spectrograph
C. J. A. P. Martins, R. Cooke, J. Liske +20
State-of-the-art 19th century spectroscopy led to the discovery of quantum mechanics, and 20th century spectroscopy led to the confirmation of quantum electrodynamics. State-of-the…
