Revisiting the statistical isotropy of GRB sky distribution
Uendert Andrade, Carlos A. P. Bengaly, Jailson S. Alcaniz +1
The assumption of homogeneity and isotropy on large scales is one of the main hypotheses of the standard cosmology. In this paper, we test the hypothesis of isotropy from the two-p…

How does an incomplete sky coverage affect the Hubble Constant variance?
Carlos A. P. Bengaly, Uendert Andrade, Jailson S. Alcaniz
We address the tension between local and the CMB measurements of the Hubble Constant using simulated Type Ia Supernova (SN) data-sets. We probe its directional depend…

A Model-independent Test of Cosmic Isotropy with Low-z Pantheon Supernovae
Uendert Andrade, Carlos A. P. Bengaly, Beethoven Santos +1
The assumption of homogeneity and isotropy on large scales is one of the main hypotheses of the standard cosmological model. In this paper, we revisit a test of cosmological isotro…
