Gravitational Matter Creation, Multi-fluid Cosmology and Kinetic Theory
S. R. G. Trevisani, J. A. S. Lima
A macroscopic and kinetic relativistic description for a decoupled multi-fluid cosmology endowed with gravitationally induced particle production of all components is proposed. The…
Can the Universe decelerate in the future?
A. A. Escobal, J. F. Jesus, S. H. Pereira +1
The possibility of an expanding decelerating Universe in the distant future is investigated in the context of a quintessence scalar field cosmology. Such a conceivable evolution is…
Dynamical model for primordial black holes
F. Ruiz, C. Molina, J. A. S. Lima
Primordial black holes are analytically and numerically discussed based on the extended McVittie spacetime solution. By assuming that dark matter and radiation are the only sources…
Extended Metastable Dark Energy
J. A. S. Lima, G. J. M. Zilioti, L. C. T. Brito
The metastable dark energy scenario is revisited by assuming that the current false vacuum energy density is the remnant from a primeval inflationary stage. The zero temperature sc…
Tsallis meets Boltzmann: q-index for a finite ideal gas and its thermodynamic limit
J. A. S. Lima, A. Deppman
Nonadditive Tsallis -statistics has successfully been applied for a plethora of systems in natural sciences and other branches of knowledge. Nevertheless, its foundations have b…
From Solar Eclipse of 1919 to the Spectacle of Gravitational Lensing
J. A. S. Lima, R. C. Santos
A century after observing the deflection of light emitted by distant stars during the solar eclipse of 1919, it is interesting to know the concepts emerged from the experiment and…
