Anisotropic singularities in modified gravity models
Michele Ferraz Figueiro, Alberto Saa
We show that the common singularities present in generic modified gravity models governed by actions of the type , with $X= -{1/2}g^{ab}\partial_aϕ\p…
Electromagnetic wave scattering by Schwarzschild black holes
Luís C. B. Crispino, Sam R. Dolan, Ednilton S. Oliveira
We analyze the scattering of a planar monochromatic electromagnetic wave incident upon a Schwarzschild black hole. We obtain accurate numerical results from the partial wave method…
Can quantum mechanics fool the cosmic censor?
G. E. A. Matsas, M. Richartz, A. Saa +2
We revisit the mechanism for violating the weak cosmic-censorship conjecture (WCCC) by overspinning a nearly-extreme charged black hole. The mechanism consists of an incoming massl…
A Field Theory Model for Dark Matter and Dark Energy in Interaction
Sandro Micheletti, Elcio Abdalla, Bin Wang
We propose a field theory model for dark energy and dark matter in interaction. Comparing the classical solutions of the field equations with the observations of the CMB shift para…
Gravitational wave recoil in Robinson-Trautman spacetimes
Rodrigo P. Macedo, Alberto Saa
We consider the gravitational recoil due to non-reflection-symmetric gravitational wave emission in the context of axisymmetric Robinson-Trautman spacetimes. We show that regular i…
A preliminary analysis of the energy transfer between the dark sectors of the Universe
Jia Zhou, Bin Wang, Diego Pavon +1
We study the mutual interaction between the dark sectors (dark matter and dark energy) of the Universe by resorting to the extended thermodynamics of irreversible processes and con…
