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…
Constraining Cosmological and Astrophysical Parameters with the Cosmic Star Formation History
Miguel Moyses, Rafael C. Nunes
Identifying new observational probes to constrain cosmological parameters has become an important goal in modern cosmology. In this work, we explore the potential of the cosmic sta…
Linear Growth of Matter Perturbations Probed by Redshift-Space Distortions in Interacting CDM Cosmologies
A. A. Escobal, H. A. P. Macedo, J. F. Jesus +2
In the context of a spatially flat CDM cosmology, we investigate interacting dark energy (IDE) scenarios characterized by phenomenological interaction terms proportional to t…
Joint Constraints on Neutrinos and Dynamical Dark Energy in Minimally Modified Gravity
Artur Ladeira, Rafael C. Nunes, Supriya Pan +1
The \(w_{\dagger}\)VCDM framework provides a theoretically well-controlled extension of \(Λ\)CDM within the class of minimally modified gravity theories, allowing for flexible cosm…
Updated Cosmological Constraints from 2D BAO Measurements: A New Compilation and Comparison with DESI DR2
Miguel A. Sabogal, Rafael C. Nunes, Felipe Avila +1
We investigate and update observational constraints on cosmological parameters within the CDM and dynamical dark energy frameworks, using a new compilation of the transverse (or…
High-redshift transverse BAO measurements with the SDSS quasar catalog
Felipe Avila, Armando Bernui, Miguel A. Sabogal +1
Transverse Baryon Acoustic Oscillation (BAO) measurements offer a robust geometric probe of the Universe expansion, presenting minimal dependence on fiducial cosmological models. I…
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…
Revisiting the temperature evolution law of the CMB with gaussian processes
Felipe Avila, Alexander Bonilla Rivera, Rafael C. Nunes +2
In this work, we perform a statistical inference of the classical background law governing the evolution of the temperature of the cosmic microwave background radiation (CMB), give…
Baryon acoustic scale at $z_{\eff} = 0.166$ with the SDSS blue galaxies
Felipe Avila, Edilson de Carvalho, Armando Bernui +2
The Baryon Acoustic Oscillations (BAO) phenomenon provides a unique opportunity to establish a standard ruler at any epoch in the history of the evolving universe. The key lies in…
Lower tensor-to-scalar ratio as possible signature of modified gravity
Abraão J. S. Capistrano, Rafael C. Nunes, Luís A. Cabral
This paper simplifies the induced four-dimensional gravitational equations originating from a five-dimensional bulk within the framework of Nash's embeddings, incorporating them in…
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…
