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…
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…
J-PLUS DR3: Galaxy-Star-Quasar classification
R. von Marttens, V. Marra, M. Quartin +20
The Javalambre Photometric Local Universe Survey (J-PLUS) is a 12-band photometric survey using the 83-cm JAST telescope. Data Release 3 includes 47.4 million sources. J-PLUS DR3 o…
One-parameter dynamical dark-energy from the generalized Chaplygin gas
Rodrigo von Marttens, Dinorah Barbosa, Jailson Alcaniz
The fact that Einstein's equations connect the space-time geometry to the total matter content of the cosmic substratum, but not to individual contributions of the matter species,…
A Test of the Standard Cosmological Model with Geometry and Growth
Uendert Andrade, Dhayaa Anbajagane, Rodrigo von Marttens +2
We perform a general test of the and cosmological models by comparing constraints on the geometry of the expansion history to those on the growth of stru…
Testing the consistency between cosmological data: the impact of spatial curvature and the dark energy EoS
Javier E. Gonzalez, Micol Benetti, Rodrigo von Marttens +1
The results of joint analyses of available cosmological data have motivated an important debate about a possible detection of a non-zero spatial curvature. If confirmed, such a res…
