The large-scale structure of the universe—the gigantic, hierarchical cosmic web of structures bound by gravity—is mostly made up of dark matter. The growth of the large-scale structure, from individual galaxies to galaxy ...
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 ...
Our best understanding of the universe is rooted in a cosmological model known as LCDM. The CDM stands for cold dark matter, where most of the matter in the universe isn't stars and planets, but a strange form of matter that ...

Since the 1960s there has been plenty of evidence to support the existence of dark matter through astrophysical and cosmological observations, and at this point we're very confident that it exists. The question remains, though: ...

This week on phys.org, we published news about muons, gigantic stellar waves, a Homo-erectus-thwarting mini ice age, and a new whale guy.
Dark matter is one of the thorniest mysteries of modern cosmology. On the one hand, astronomers have gathered a wealth of supporting evidence through galaxy clustering statistics, gravitational lensing, and cosmic microwave ...
