Revisiting Unimodular Quantum Cosmology
Júlio C. Fabris, Luiz Filipe Guimarães, Nelson Pinto-Neto +1
The quantization of unimodular gravity in minisuperspace leads to a time evolution of states generated by the Hamiltonian, as in usual quantum mechanics. We revisit the analysis ma…
Fluid and scalar field representations in the Brans-Dicke theory: cosmological scenarios
Tiago H. B. Alves, Júlio C. Fabris, Luiz Filipe Guimarães
The Brans-Dicke scalar-tensor cosmological models are studied in both Einstein and Jordan frames, using hydrodynamical and self-interacting scalar field representations of the ener…
The frozen vanilla model: Exploring dark sector interactions with delta effective theories
Martín G. Richarte, Luiz F. Guimarães, Susana J. Landau +1
In this paper, we introduce a new interacting mechanism within the dark sector, encompassing both dark energy and dark matter, while grounding our analysis in the familiar framewor…
Quasar Pairs as Large--Scale Structure tracers
Martín G. Richarte, Facundo Toscano, Diego G. Lambas +3
Quasars are effective tracers of the large-scale distribution of galaxies at high redshift thanks to their high luminosity and dedicated surveys. Previous studies have shown that q…
