Hubble tension problem encompassed by phase-space quantum cosmology
Alex E. Bernardini
The paper proposes a phase‑space quantum cosmology framework using Weyl–Wigner mechanics to derive quantum corrections to the Friedmann equation that can reduce the discrepancy bet…
On dark sector scalar field theories driven by cosmological -fields
Alex E. Bernardini, Orfeu Bertolami
The interplay of Hoyle-Narlikar (HN) creation field cosmology and scalar field models for the dark sector, including the generalized Chaplygin Gas (GCG), is investigated . Though o…
On Scalar Cosmological Perturbations in Non-Minimally Coupled Weyl Connection Gravity
M. Lima, C. Gomes
We analyze a theory with non-minimal matter-curvature coupling, considering non-metricity properties with a Weyl connection. This model has the advantage of an extra force term whi…
Testing the Dark Universe through the Layzer-Irvine Equation
Cláudio Gomes
We review the cosmic generalisation of the virial theorem known as the Layzer-Irvine equation, also independently derived by Dmitriev and Zeldovich. This equation has been studied…
Cosmological and lunar laser ranging constraints on evolving dark energy in a nonminimally coupled curvature-matter gravity model
Riccardo March, Miguel Barroso Varela, Orfeu Bertolami +3
We analyze a cosmological solution to the field equations of a modified gravity model where curvature and matter are nonminimally coupled. The current Universe's accelerated expans…
Accretion of Generalized Chaplygin Gas onto Cosmologically Coupled Black Holes
Luis F. Reis, Mario C. Baldiotti, Orfeu Bertolami
We study the accretion of cosmic dark fluids, responsible for driving the accelerated expansion of the universe, onto cosmologically coupled black holes. More specifically, we focu…
