Galactic Accelerations from the GD-1 Stream Suggest a Tilted Dark Matter Halo
Cold dark matter halos are expected to be triaxial and often tilted relative to the stellar disk. Stellar streams provide a sensitive tracer of the Milky Way's halo shape, though models for the Galact...

From moving groups to star formation in the Solar Neighborhood
Moving groups in the solar neighborhood are ensembles of co-moving stars, likely originating due to forces from spiral arms, the Galactic bar, or external perturbations. Their co-movement with young c...
