Wormholes Immersed in Rotating MatterChristian Hoffmann1, Theodora Ioannidou2, Sarah Kahlen1, •Burkhard Kleihaus1, and Jutta Kunz11Institut für Physik, Universität Oldenburg, Germany — 2Aristotle University of Thessaloniki, Thessaloniki, Greece

We demonstrate that rotating matter sets the throat of an Ellis wormhole into rotation, allowing for wormholes which possess full reflection symmetry with respect to the two asymptotically flat spacetime regions. We analyse the properties of this new type of rotating wormholes and show that the wormhole geometry can change from a single throat to a double throat configuration. We further discuss the ergoregions and the lightring structure of these wormholes.
