Abstract

We investigate the thin-shell wormholes constrained by cosmological observations for the first time in the literature. Without loss of generality, we study the thin-shell wormholes in ω\omegaCDM model and analyze their stability under perturbations preserving the symmetry. Firstly, we constrain the ω\omegaCDM model using a combination of Union 2.1 SNe Ia data, the latest H(z)H(z) data and CMB data. Secondly, we use the constrained dark energy equation of state (EoS) ω\omega which lies in [1.05,0.89][-1.05,-0.89] to investigate thin-shell wormholes of various black hole spacetimes. We find that the stable Schwarzschild and Reinssner-Nordstr\"{o}m thin-shell wormholes constrained by cosmological observations do not exist. In addition, the method we developed can be applied into exploring the stable thin-shell wormholes from any black hole spacetime in the framework of any cosmological theory.
