Probing cosmic isotropy: Hubble constant and matter density large-angle variations with the Pantheon+SH0ES data
Rahima Mokeddem, Maria Lopes, Felipe Avila +2
In this study we investigate potential large-angle anisotropies in the angular distribution of the cosmological parameters (the Hubble constant) and (the matter densit…
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…
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…
Measuring the matter fluctuations in the Local Universe with the ALFALFA catalog
Camila Franco, Jezebel Oliveira, Maria Lopes +2
The standard model of cosmology describes the matter fluctuations through the matter power spectrum, where , defined at the scale of $8…
