Can wormhole spacetimes in Unimodular Gravity be supported by ordinary matter? A general proof of the exotic matter requirement
Mauricio Cataldo, Norman Cruz, Patricio Salgado
We establish a general no--go theorem demonstrating that all traversable wormhole configurations in Unimodular Gravity necessarily require exotic matter. The proof relies solely on…

Revisiting Wormhole Solutions in Unimodular Gravity: Energy Conditions and Exotic Matter Requirements
Mauricio Cataldo, Norman Cruz
The paper entitled Unimodular Gravity Traversable Wormholes by Agrawal et al. examined the properties of barotropic wormholes without tidal forces within the framework of Unimodula…

Light propagation around a Kerr-like black hole immersed in an inhomogeneous anisotropic plasma in Rastall gravity: Analytical solutions to the equations of motion
Mohsen Fathi, Marco Olivares, José R. Villanueva +1
In this paper, we explore the behavior of light ray trajectories in the exterior geometry of a rotating black hole within the Rastall theory of gravity, which is surrounded by an i…
