The authors begin by looking at data from the TNG50 run of the IllustrisTNG simulations. These are supercomputer simulations of galactic evolution that include cosmological evolution and dark matter as well as detailed magnetohydrodynamic interactions. From this data, the authors show that the inner region of the dark matter halo can be significantly tilted relative to the galactic plane and that these can be caused both by galactic collisions and near misses between galaxies.
Astronomers have observed other galaxies with a warped plane, and there is some evidence that as many as half of spiral galaxies in the Universe are warped to some degree. This suggests the influence of long-term and common gravitational interactions between a galaxy and its twisted halo. Of course, this is just one study, so further observations and simulations will be needed to understand the details of how many galaxies such as the Milky Way evolve.
