Modified Gravity from growth data: goodness-of-fit and gravitational coupling
Manoel V. S. Filho, Fernanda Oliveira, Wiliam S. Hipólito-Ricaldi +2
While background expansion data alone cannot discriminate among cosmological models, the growth of large-scale structures directly probes the underlying theory of gravity, offering…
Testing Scale-Dependent Suppression of Structure Growth in the Linear Regime
Fernanda Oliveira, Miguel A. Sabogal, Felipe Avila +2
We investigate recent reports of a suppression in the growth rate of cosmic structures inferred from analyses of the dataset. To address this issue, we explore the hypo…
Probing the Cosmic Distance Duality Relation via Non-Parametric Reconstruction for High Redshifts
Felipe Avila, Fernanda Oliveira, Camila Franco +4
We test the validity of the cosmic distance duality relation (CDDR) by combining angular diameter distance and luminosity distance measurements from recent cosmological observation…
Is CDM a good model for the clumpy Universe?
Fernanda Oliveira, Felipe Avila, Camila Franco +1
The DESI collaboration just obtained a set of precise BAO measurements, that combined with CMB and SNIa datasets show that the CDM model is preferred over CDM, at more…
Viability of general relativity and modified gravity cosmologies using high-redshift cosmic probes
Fernanda Oliveira, Bruno Ribeiro, Wiliam S. Hipólito-Ricaldi +2
Several models based on General Relativity and Modified Gravity aim to reproduce the observed universe with precision comparable to the flat-CDM cosmological model. In this stud…
Reconstructing the growth index with Gaussian Processes
Fernanda Oliveira, Felipe Avila, Armando Bernui +2
Alternative cosmological models have been proposed to alleviate the tensions reported in the concordance cosmological model, or to explain the current accelerated phase of the univ…
