Anthropic versus cosmological solutions to the coincidence problem
A. Barreira, P. P. Avelino
In this paper we investigate possible solutions to the coincidence problem in flat phantom dark energy models with a constant dark energy equation of state and quintessence models…

Gravitational Effects of Varying Alpha Strings
J. Menezes, P. P. Avelino, C. Santos
We study spatial variations of the fine-structure constant in the presence of static straight cosmic strings in the weak-field approximation in Einstein gravity. We work in the con…

Cosmic strings in Bekenstein-type models
J. Menezes, P. P. Avelino, C. Santos
We study static cosmic string solutions in the context of Bekenstein-type models. We show that there is a class of models of this type for which the classical Nielsen-Olesen vortex…
