Probing dark fluids and modified gravity with gravitational lensing
L. Perivolaropoulos, I. Antoniou, D. Papadopoulos
We generalize the Rindler-Ishak (2007) result for the lensing deflection angle in a SdS spacetime, to the case of a general spherically symmetric fluid beyond the cosmological cons…

Stabilizing Spherical Energy Shells with Angular Momentum in Gravitational Backgrounds
I. Antoniou, D. Kazanas, D. Papadopoulos +1
Spherical energy shells in General Relativity tend to collapse due to gravitational effects and/or due to tension effects. Shell stabilization may be achieved by modifying the grav…
