Evolution of Primordial Black Holes in a radiation and phantom energy environment
Daniel C. Guariento, J. E. Horvath, P. S. Custódio +1
In this work we extend previous work on the evolution of a Primordial Black Hole (PBH) to address the presence of a dark energy component with a super-negative equation of state as…
Supermassive black holes may be limited by the Holographic Bound
Paulo Sergio Custodio, J. E. Horvath
Supermassive Black Holes are the most entropic objects found in the universe. The Holographic Bound (HB) to the entropy is used to constrain their formation time with initial masse…
Holographic Principle bounds on Primordial Black Hole abundances
P. S. Custodio, J. E. Horvath
The generalized Second Law of thermodynamics and the Holographic Principle are combined to obtain the maximum mass of black holes formed inside a static spherical box of size f…
The evolution of primordial black hole masses in the radiation- dominated era
P. S. Custodio, J. E. Horvath
We revisit the problem of PBH mass evolution in the radiation-dominated era. We solve the complete differential equation in the semiclassical regime with absorption and evaporation…
Evolution of a Primordial Black Hole Population
P. S. Custodio, J. E. Horvath
We reconsider in this work the effects of an energy absorption term in the evolution of primordial black holes (hereafter PBHs) in the several epochs of the Universe. A critical ma…
