BLUF: Research conducted by Harvard astronomers provides explanations for the warping and flaring edges of the Milky Way galaxy, attributing it to the existence of a tilted, elliptical halo of dark matter encompassing the galaxy.
OSINT: We frequently picture the Milky Way as a spinning, flat disk comprised of various elements such as stars, dust, and gas. However, if you were to picture it from a different perspective, the galaxy displays a distinctive warp, resembling a bent and twisted vinyl LP. The reasoning behind this unusual shape, long observed by scientists, has remained a mystery until recently. Now, a team of researchers from Harvard’s Center for Astrophysics presents the first explanation for this enigma. They propose that the Milky Way is shrouded in an irregularly aligned dark matter halo, a claim that strengthens current theories about the galaxy’s evolution and could hint at the nature of elusive dark matter.
The research led by Jiwon Jesse Han, with co-authors Charlie Conroy and Lars Hernquist, paints a picture of our galaxy existing within a stellar halo. This cloud extends far out into the universe and is believed to be tilted and elliptical, resembling a zeppelin or football in shape. Extending from this assumption, the team deduces that the dark matter halo, enclosing the galaxy and its surroundings, shares the same shape. Dark matter, invisible to us as it fails to interact with light, constitutes 80% of the galaxy’s mass. But, through models computing the star orbits within a slanted, oblong-shaped dark matter halo, a resemblance is observed that echoes the warped and flared galaxy attributes visible to us.
Scientists have hypothesized in the past that the Milky Way is the product of a collision between galaxies. This new research adds weight to this theory. Moreover, calculations about the dark matter halo’s probable form could lead to breakthroughs in understanding dark matter’s properties and particle nature, leading to smarter ways to study the universe’s majority matter: dark matter.
