The abstract, sentence by sentence

We consider wormhole geometries subject to a gravitational action consisting of non-linear powers of the Ricci scalar. Specifically, wormhole throats are studied in the case where Einstein gravity is supplemented with a Ricci-squared and inverse Ricci term. In this modified theory it is found that static wormhole throats respecting the weak energy condition can exist. The analysis is done locally in the vicinity of the throat, which eliminates certain restrictions on the models introduced by considering the global topology.

The paper

Original abstract

We consider wormhole geometries subject to a gravitational action consisting of non-linear powers of the Ricci scalar. Specifically, wormhole throats are studied in the case where Einstein gravity is supplemented with a Ricci-squared and inverse Ricci term. In this modified theory it is found that static wormhole throats respecting the weak energy condition can exist. The analysis is done locally in the vicinity of the throat, which eliminates certain restrictions on the models introduced by considering the global topology.

Observing of background electromagnetic radiation of the real sky through the throat of a wormhole
gr-qc 2024-12 conditional novelty 5.0 of 10

A simulation shows that a nearby wormhole mouth would project a lensed image of the real CMB sky and Milky Way inside its silhouette, offering a possible observational signature distinct from a black hole.
Static spherically symmetric solutions in mimetic gravity: rotation curves & wormholes

Mimetic gravity with a suitably chosen potential can host the linear and quadratic metric corrections that fit flat galactic rotation curves without particle dark matter.
Stable Lorentzian Wormholes in Dilatonic Einstein-Gauss-Bonnet Theory
hep-th 2011-11 conditional novelty 5.0 of 10

Dilatonic Einstein-Gauss-Bonnet gravity in four dimensions admits a two-parameter family of traversable wormholes, a subset of which is linearly stable to radial perturbations.
Exotic solutions in General Relativity: Traversable wormholes and 'warp drive' spacetimes
gr-qc 2007-10 accept novelty 2.0 of 10

Traversable wormholes, warp drives, and Krasnikov tubes all require stress-energy that violates the null energy condition, and quantum-inequality bounds push macroscopic versions of them out of reach.
