Renormalization group corrections to CDM model and observational consequences for tension
Nicolas R. Bertini, Marcos H. Novaes, Rodrigo von Marttens +1
We explore the renormalization group-based extension of the CDM model as a potential solution to the current cosmological tensions. In this approach, both the cosmological const…
J-PLUS: Bayesian object classification with a strum of BANNJOS
A. del Pino, C. López-Sanjuan, A. Hernán-Caballero +22
With its 12 optical filters, the Javalambre-Photometric Local Universe Survey (J-PLUS) provides an unprecedented multicolor view of the local Universe. The third data release (DR3)…
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…
CMB constraints on inflection-point inflation with a pseudo-scalar dark matter
Jamerson G. Rodrigues, Vinícius Oliveira, Rodrigo von Marttens +2
In this work, we investigate the physical aspects of the inflection-point inflation scenario and assess its observational viability in light of current Cosmic Microwave Background…
