The homogeneity scale in the Local Universe: model-independent estimate from S-PLUS DR4 blue galaxies
Camila Franco, Felipe Avila, Armando Bernui +8
We present a model-independent estimate of the angular homogeneity scale in the Local Universe by analysing data from the Southern Photometric Local Universe Survey (S-PLUS). Two c…
Probing large-scale structures with the two-point function and the power spectrum: insights into cosmic clustering evolution
Camila Franco, Felipe Avila, Armando Bernui
Understanding the large-scale structure of the Universe requires analyses of cosmic clustering and its evolution over time. In this work, we investigate the clustering properties o…
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 mo…
A cosmology weakly dependent measurement of 2D Baryon Acoustic Oscillations scale from the Southern Photometric Local Universe Survey
U. Ribeiro, F. Avila, C. R. Bom +8
Baryon Acoustic Oscillations (BAO) provide a robust standard ruler for observational cosmology, enabling precise constraints on the expansion history of the Universe. We present a…
Dipolar fluence distribution of statistically isotropic FERMI gamma-ray bursts
Maria Lopes, Armando Bernui, Wiliam S. Hipólito-Ricaldi +2
We investigated the large-angle distribution of the gamma-ray bursts (GRBs) from the updated FERMI/GBM catalog to probe the statistical isotropy of these astrophysical transient ev…
