Inhomogeneous dust collapse in five-dimensional AdS-Chern-Simons gravity
Luis Avilés, José Díaz, Cristian Quinzacara +1
We study the gravitational collapse of a spherically symmetric, inhomogeneous dust cloud in five-dimensional AdS Chern--Simons gravity. Working in the torsion-free sector and using…
Non-exotic traversable wormholes in Einstein-Chern-Simons gravity
Mauricio Cataldo, Fernando Goméz, Paola Meza +2
We investigate traversable wormhole solutions in five-dimensional Einstein-Chern-Simons (EChS) gravity, a gauge-theoretic extension of General Relativity that introduces a higher-c…
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…
