Primordial black hole evolution in two-fluid cosmology
Eduardo M. Gutiérrez, Florencia L. Vieyro, Gustavo E. Romero
Several processes in the early universe might lead to the formation of primordial black holes with different masses. These black holes would interact with the cosmic plasma through…
Cosmic reionization by primordial cosmic rays
Matias Tueros, Maria Victoria del Valle, Gustavo Esteban Romero
After the so-called cosmic recombination, the expanding universe entered into a period of darkness since most of the matter was in a neutral state. About a billion years later, how…
Structure of neutron stars in R-squared gravity
Mariana Orellana, Federico García, Florencia Anabella Teppa Pannia +1
The effects implied for the structure of compact objects by the modification of General Relativity produced by the generalization of the Lagrangian density to the form f(R)=R+αR^2,…
Accretion disks around black holes in modified strong gravity
Daniela Pérez, Gustavo E. Romero, Santiago E. Perez Bergliaffa
Stellar-mass black holes offer what is perhaps the best scenario to test theories of gravity in the strong-field regime. In particular, f(R) theories, which have been widely discus…
An analysis of a regular black hole interior model
Daniela Pérez, Gustavo E. Romero, Santiago E. Perez Bergliaffa
We analyze the thermodynamical properties of the regular static and spherically symmetric black hole interior model presented by Mboyne and Kazanas. Equations for the thermodynamic…
Gravitational entropy of black holes and wormholes
Gustavo E. Romero, Romain Thomas, Daniela Pérez
Pure thermodynamical considerations to describe the entropic evolution of the universe seem to violate the Second Law of Thermodynamics. This suggests that the gravitational field…
