A trio of astrophysicists with Harvard and Smithsonian's Center for Astrophysics has found via computer modeling that the likely reason for the warp and flare of the Milky Way galaxy is a tilt of the dark halo. In their paper published in the journal Nature Astronomy, Jiwon Jesse Han, Charlie Conroy and Lars Hernquist describe their theories regarding the shape of the Milky Way galaxy and what their model showed.
Present-day distribution of simulated stars in Galactocentric cylindrical coordinates. Negative R indicates azimuthal angles within 90∘ of the northern warp, and positive R indicates azimuthal angles within 90∘ of the southern warp. The top panel shows the warp and the bottom panel shows the vertical deviation from the average warp. The vertical deviation systematically increases towards the outer Galaxy, demonstrating the flare of the disk.
When astronomers first figured out that the solar system is part of a larger spiral galaxy—the Milky Way—they assumed that the galaxy was flat. More recent data from telescopes and probes has shown that the Milky Way is slightly warped, mostly near the end tips of its spiral arms. And the most recent data from ESA's Gaia space telescope shows that one side of the galaxy bends slightly up while the other side bends slightly down.
The research team began by noting that some recent data has shown that the galactic halo is somewhat off-kilter compared to the disk that makes up the Milky Way. This suggested to them that the only thing that could have caused the halo to become unbalanced in such a way would be an imbalance in the dark matter that is believed to permeate the galaxy.to represent the Milky Way, starting from its earliest days, when it was still forming.
They found that the Milky Way slowly formed into its current shape, strongly bolstering their theory. They further suggest that the tilt in the
