Nonsingular Decaying Vacuum Cosmology and Entropy Production
J. A. S. Lima, S. Basilakos, Joan Solà
The thermodynamic behavior of a decaying vacuum cosmology describing the entire cosmological history evolving between two extreme (early and late time) de Sitter eras is investigat…
Gravitationally Induced Particle Production: Thermodynamics and Kinetic Theory
J. A. S. Lima, I. P. Baranov
A relativistic kinetic description for the irreversible thermodynamic process of gravitationally induced particle production is proposed in the context of an expanding Friedmann-Ro…
Cosmic acceleration without dark energy: Background tests and thermodynamic analysis
J. A. S. Lima, L. L. Graef, D. Pavón +1
A new cosmic scenario with gravitationally induced particle creation is proposed. In this model the Universe evolves from an early to a late time de Sitter era, with the recent acc…
A unified solution to the small scale problems of the CDM model
A. Del Popolo, J. A. S. Lima, Julio C. Fabris +1
We study, by means of the model proposed in Del Popolo (2009), the effect of baryon physics on the small scale problems of the CDM model. We show that, using this model, the cusp/c…
