Do DESI-DR2 BAO data imply a coupling of dark matter and dark energy?
Weiqiang Yang, Sibo Zhang, Dinorah Barbosa +3
We revisit an interacting dark matter (DM) -- dark energy (DE) model characterized by the interaction function , where is a constant coupling parameter and is t…
Assessing the dark degeneracy through the gas mass fraction data
Dinorah Barbosa, Rodrigo von Marttens, Javier Gonzalez +1
It is well-known that Einstein's equations constrain only the total energy-momentum tensor of the cosmic substratum, without specifying the characteristics of its individual consti…
One-parameter dynamical dark-energy from the generalized Chaplygin gas
Rodrigo von Marttens, Dinorah Barbosa, Jailson Alcaniz
The fact that Einstein's equations connect the space-time geometry to the total matter content of the cosmic substratum, but not to individual contributions of the matter species,…
