$f({\sf R})$ Gravity Wormholes sourced by a Phantom Scalar Field
TL;DR: In this article, an exact wormhole spacetime supported by a phantom scalar field in the context of gravity was derived, and the resulting model is free of ghosts and avoids the tachyonic instability.

The Effect of Bulk Tachyon Field on the Dynamics of Geometrical Tachyon
TL;DR: In this paper, the authors studied the dynamics of the geometrical tachyon field on an unstable D3-brane in the background of a bulk tachon field of a D3brane solution of Type-0 string theory.
Stealth Ellis Wormholes In Horndeski theories
TL;DR: In this article , the authors revisited the well studied Ellis wormhole solution in a generalized Horndeski theory motivated from the Kaluza-Klein compactification procedure of the more fundamental higher dimensional Lovelock gravity.

Superradiance Effect of a Black Hole Immersed in an Expanding Universe
TL;DR: In this paper, the authors studied the superradiance effect of a charge black hole immersed in an expanding universe and found that it has the same effect in both epochs of the expansion of the universe.
