The halo of dark matter that is thought to surround the Milky Way appears to be shaped like a squashed beach ball, astronomers have found.

An invisible halo of misaligned dark matter could explain the warps at the Milky Way's edges. A gigantic blob of invisible dark matter has bent our galaxy out of shape, a new study suggests ...

In particular, they speculated that some vortex lines might extend beyond a single halo, connecting galaxies through the vast filaments of the cosmic web — the gigantic tendrils of dark matter that ...

This galactic halo is dominated by invisible dark matter, whose presence is only measurable through the gravity that it exerts. Every galaxy has its own halo of dark matter.

The researchers had, at that time, inferred that the shape of that dark matter halo would be similar to the stellar halo (with a matching tilt) albeit much wider.

Aug. 5, 2022 — According to the standard model of cosmology, the vast majority of galaxies are surrounded by a halo of dark matter particles. This halo is invisible, but its mass exerts a strong ...

According to data collected as part of the H3 Survey and by the Gaia spacecraft, the halo is not a sphere. It is more oblate and tilted, resembling a kicked ball. The team tracked 5,559 stars that ...

Scientists believe that the shape of the dark matter halo is key to understanding the hierarchical formation of the Milky Way. Despite extensive efforts in recent decades, ...

If dark matter was indeed self-annihilating, it would show up in Fermi’s observations. The next year, Slatyer and Finkbeiner used Fermi’s public data to hunt for the stuff.

To dark matter and dark energy, add dark galaxies — collections of stars so sparse and faint that they are all but invisible. An artist’s depiction of hydrogen gas observed in the galaxy J0613 ...
