An international team of researchers has found dark matter dominating the halos of two supermassive black holes in galaxies ...

New research from the SAGA Survey, comparing the Milky Way with 101 similar galaxies, unveils how our galaxy differs ...

A perplexing "break" in a stream of stars around the Milky Way could be the result of dark matter — that is, if the mysterious cosmic stuff interacts with itself. The feature in question is in the ...

Now, a team from the University of California, Riverside, proposes that the cause of this feature is a sub-halo of self-interacting dark matter within the larger halo of dark matter that envelops ...

This puzzling result makes sense if one assumes that the boundary stars are feeling the gravitational effects of an unseen mass—dark matter—in a halo around the galaxy. Dark matter could also ...

Another possibility is that dark matter is not WIMPs, but MACHOs. These Massive Astrophysical Compact Halo Objects are large bodies made of ordinary matter put together in unexpected ways that ...

6, 2025 — Physicists have proposed a solution to a long-standing puzzle surrounding the GD-1 stellar stream, one of the most well-studied streams within the galactic halo of the Milky ...
