Warp, waves, and wrinkles in the Milky Way

Abstract:

We derive unbiased distance estimates for the Gaia-TGAS data set by correcting for the bias due to the distance dependence of the selection function, which we measure directly from the data. From these distances and proper motions, we estimate the vertical and azimuthal velocities, W and Vφ, and angular momentum Lz for stars in the Galactic centre and anticentre directions. The resulting mean vertical motion W¯¯¯¯¯ shows a linear increase with both Vφ and Lz at 10σ significance. Such a trend ...
