THE<i>GAIA</i>INERTIAL REFERENCE FRAME AND THE TILTING OF THE MILKY WAY DISK
While the precise relationship between the Milky Way disk and the symmetry planes of the dark matter halo remains somewhat uncertain, a time-varying disk orientation with respect to an inertial reference frame seems probable. Hierarchical structure formation models predict that the dark matter halo is triaxial and tumbles with a …
