Hubble tension and small-scale inhomogeneities on light propagation
Lucila Kraiselburd, Cassio Pigozzo, Susana J. Landau +1
Context. A major observational challenge within the standard cosmological framework is the Hubble tension, a statistically significant () disagreement between the Hubble c…
Fully-heavy tetraquarks in the vacuum and in a hot environment
Vinícius S. Silva, Cássio Pigozzo, Luciano M. Abreu
We study the thermal behavior of quarkonia and fully-heavy tetraquark states associated to the charmonium, bottomonium and bottom-charmonium mass spectra. The starting point is the…
Dark sector interactions in light of weak lensing data
M. Benetti, P. T. Z. Seidel, C. Pigozzo +3
The current observational tensions in the standard cosmological model have reinforced the research on dynamical dark energy, in particular on models with non-gravitational interact…
Testing the isotropy of cosmic acceleration with Pantheon+ and SH0ES: A cosmographic analysis
Carlos A. P. Bengaly, Cássio Pigozzo, Jailson S. Alcaniz
We use a recent Pantheon+SH0ES compilation of Type Ia Supernova distance measurements at low-redshift, i.e., , in order to investigate the directional depend…
Active galactic nuclei and gravitational redshifts
N. D. Padilla, S. Carneiro, J. Chaves-Montero +4
Context: Gravitational redshift is a classical effect of Einstein's General Relativity, already measured in stars, quasars and clusters of galaxies. Aims: We here aim to identify t…
Testing the growth rate in homogeneous and inhomogeneous interacting vacuum models
H. A. Borges, C. Pigozzo, P. Hepp +2
In this work we consider a class of interacting vacuum corresponding to a generalised Chaplygin gas (gCg) cosmology. In particular we analyse two different scenarios at perturbatio…
