# Double shadows of reflection-asymmetric wormholes supported by positive energy thin-shells

@article{Guerrero2021DoubleSO, title={Double shadows of reflection-asymmetric wormholes supported by positive energy thin-shells}, author={Merce Guerrero and Gonzalo J. Olmo and Diego Rubiera-Garc{\'i}a}, journal={Journal of Cosmology and Astroparticle Physics}, year={2021}, volume={2021} }

We consider reflection-asymmetric thin-shell wormholes within Palatini f(R) gravity using a matching procedure of two patches of electrovacuum space-times at a hypersurface (the shell) via suitable junction conditions. The conditions for having (linearly) stable wormholes supported by positive-energy matter sources are determined. We also identify some subsets of parameters able to locate the shell radius above the event horizon (when present) but below the photon sphere (on both sides). We…
