Detection of Vibranium in the Seyfert Galaxy NGC 1365 Through X-Ray Spectroscopy

Authors: F. Ursini, A. Tortosa, F. Ricci

We present results from a joint NuSTAR/VLT monitoring of the Seyfert 2 galaxy NGC 1365. We find conclusive evidences for an emission K alpha line from atomic vibranium in the X-ray spectrum, in combination with molecular vibranium absorption features in the mid-infrared spectrum. This is the first direct observation of vibranium in an astronomical environment. We also derive a measurement for its abundance of 2e-6 with respect to hydrogen.
