Dark Matter

This wide field shows the extended stellar halo of NGC 6505 and showcases the Einstein ring, surrounded by colourful foreground stars and background galaxies.

The image shows the predicted flux of antihelium-3 produced from dark matter (WIMPs) that annihilate producing these antinuclei. Each color represents the prediction for a different mass of dark matter, as shown in the legend. t The bands are almost touching the AMS-02 sensitivity, which means that in some optimistic cases, WIMPs can explain this discrepancy.

Velocity streamlines within the reconstructed volume, with colored envelopes associated with the prominent nearby basins of attraction. The map and streamlines have been cropped to the region covered by Cosmicflows-4 data. The streamlines within a given basin converge onto the region of high concentration of galaxies.

An artist’s illustration depicts a primordial black hole (at left) flying past, and briefly “wobbling” the orbit of Mars (at right), with the sun in the background. MIT scientists say such a wobble could be detectable by today’s instruments. Credits:Credit: Image by Benjamin Lehmann, using SpaceEngine @ Cosmographic Software LLC.

One of the few galaxies with a well-studied stellar halo is our neighbor, Andromeda, depicted here in the graphic. The reason Andromeda’s halo can be investigated so thoroughly is simply a matter of distance, both being close enough and bright enough that we can see the full picture with our current class of telescopes.

This artist's concept shows what happened when two massive clusters of galaxies, collectively known as MACS J0018.5, collided: The dark matter in the galaxy clusters (blue) sailed ahead of the associated clouds of hot gas, or normal matter (orange). Both dark matter and normal matter feel the pull of gravity, but only the normal matter experiences additional effects like shocks and turbulence that slow it down during collisions.

This image shows two panels side by side. The right panel illustrates a spinning top precessing due to gravitational force. The left panel depicts the Galactic disk warp, which behaves similarly to the spinning top. The warp moves in a graceful pattern under the influence of the dark matter halo's gravitational pull. This illustration was created by HOU Kaiyuan and DONG Zhanxun from Shanghai Jiao Tong University.
