CDM is still the standard model for dark matter because it works for building and maintaining cosmic structures such as galaxies. If dark matter is cold, then it can clump up and aggregate more ...

But axions were pushed aside as the WIMPs hypothesis gained more steam. Back-of-the-envelope calculations showed that the ...

Matter in intergalactic space is not randomly scattered - it forms a vast network of filamentary structures that make up the ...

The remaining 85% of dark matter would still behave as the standard cold dark matter model predicts, preserving the successes of existing observations. Implications for Cosmology and Future Research.

Researchers, in a recent Physical Review Letters paper, introduce a new mechanism that may finally allow ultralight dark ...

Their study, published in Nature, poses new challenges to the prevailing galaxy formation models within the Λ-Cold Dark Matter (ΛCDM) framework.

Dark matter, the most mysterious "stuff" in the universe, may be a sort of cosmic matchmaker, allowing supermassive black holes to overcome a final hurdle before colliding and merging into one ...

Our best theoretical model for the universe, the Lambda/Cold Dark Matter model (“ΛCDM”), predicts a value for H 0 of 67–68 km/s/Mpc. Our observations, however, put H 0 at around 73 km/s/Mpc.

"Cold dark matter sub-halos typically lack the density needed to produce the distinctive features observed in the GD-1 stream,” Yu explained.

Researchers propose a new theory for the origin of dark matter, the invisible substance thought to give the universe its shape and structure. Their mathematical models show that dark matter could ...
