(Phys.org)—A collaborative of researchers from several U.S. universities has published a new paper that explains the major contradictions presented by the prevailing cold dark matter (CDM) cosmological model, and proposes ...
A new, large-scale computer simulation has shown for the first time that large disk galaxies, much like our own Milky Way, may have existed in the early days of the universe.

One of the main predictions of the current model of the creation of structures in the universe, known at the Lambda Cold Dark Matter model, is that galaxies are embedded in very extended and massive halos of dark matter that ...

A team of researchers working at the Centre for Cold Matter, Blackett Laboratory, Imperial College London, has found a way to chill molecules much closer to absolute zero. In their paper published in the journal Nature Physics, ...
Subtle distortions hidden in ALMA's stunning image of the gravitational lens SDP.81 are telltale signs that a dwarf dark galaxy is lurking in the halo of a much larger galaxy nearly 4 billion light-years away. This discovery ...

Dark matter halos are theoretical bodies inside which galaxies are suspended; the halo's mass dominates the total mass. These halos cannot be observed directly, but astronomers infer their presence by the phenomenon of gravity ...
