No slow-roll inflation à la Generalized Chaplygin Gas in General Relativity
Alexander Gallego Cadavid, J. R. Villanueva
The Generalized Chaplygin Gas (GCG) model is characterized by the equation of state , where and . The model has been extensively studied due to its inter…
Classical tests on a charged Weyl black hole: bending of light, Shapiro delay and Sagnac effect
Mohsen Fathi, Marco Olivares, J. R. Villanueva
In this paper, we apply the classical test of general relativity on a charged Weyl black hole, whose exterior geometry is defined by altering the spherically symmetric solutions of…
Gravitational lensing in dispersive media and deflection angle of charged massive particles in terms of curvature scalars and energy-momentum tensor
Gabriel Crisnejo, Emanuel Gallo, José R. Villanueva
In this work we extend the approach used in [Emanuel Gallo and Osvaldo M. Moreschi, Phys. Rev. D 83, 12 083007 (2011)] to the study of weak gravitational lensing in a plasma medium…
Photons trajectories on a first order scale-dependent static BTZ black hole
Mohsen Fathi, Ángel Rincón, J. R. Villanueva
In this paper we study the motion of massless particles on a static BTZ black hole background in the context of scale-dependent gravity, which is characterized by the running param…
