Jormungandr: A Large Substructure Circling the Milky Way Identified from Gaia DR3 Data
We report the discovery of a large substructure in the Milky Way passing through the solar neighborhood, detected in actions $\left({J}_{\phi },{J}_{{\rm{R}}}\right)$ calculated from Gaia DR3 data. We perform extensive tests to evaluate the selection effects present in the sample and conclude that t...
