The study of traversable wormholes is very hot topic for the past 30 years. One of
the best possible way to make traversable wormhole is using the thin-shells to cut
and paste two spacetime which has tunnel from one ...

Despite impressive phenomenological success, cosmological models are incomplete without an understanding of what happened at the big bang singularity. Maxwell electrodynamics, considered as a source of the classical Einstein ...

This paper is devoted to the study of radiation of massive spin-2 boson (graviton with a nonzero mass) through the event horizon of a generic static and spherically symmetric black hole in (3+1) dimensions. To this end, ...

(Springer, 2016-05-30)
In this paper, we investigate the tunneling process of charged massive bosons W± (spin-1 particles) from noncommutative charged black holes such as charged RN black holes and charged BTZ black holes. By applying the WKB ...

We study the quantum tunneling of charged massive vector bosons from a charged static and a rotating black string. We apply the standard methods, first we use the WKB approximation and the Hamilton-Jacobi equation, and ...

In this paper, we model a canonical acoustic thin-shell wormhole (CATSW) in the framework of analogue gravity systems. In this model, we apply cut and paste technique to join together two spherically symmetric, analogue ...

Using a black hole with scalar hair, we construct a scalar thin-shell wormhole (TSW) in 2+1 dimensions by applying the Visser cut and paste technique. The surface stress, which is concentrated at the wormhole throat, is ...

The unbounded center-of-mass (CM) energy of oppositely moving colliding particles near horizon emerges also in 1+1 -dimensional Horava-Lifshitz gravity. This theory has imprints of renormalizable quantum gravity characteristics ...
