In this visualization, each dot represents a gas parcel with a mass approximately 1,000 times that of the Sun in the simulation of the cosmic Dark Ages. The left and right panels compare the cold and ...

Galaxies are far more than the sum of their stars. Long before stars even formed, dark matter clumped up and drew regular matter together with its gravity, providing the invisible scaffolding upon ...

Dark energy is responsible for the expansion of the Universe, but its true nature is still a subject of much debate. Computer simulations based on the latest astronomical data enable scientists to ...

A cosmological simulation study by researchers from the Shanghai Astronomical Observatory of the Chinese Academy of Sciences has systematically revealed, for the first time, how the interaction ...

Physicists have unveiled a new way to simulate a mysterious form of dark matter that can collide with itself but not with normal matter. This self-interacting dark matter may trigger a dramatic ...

Understanding the universe as a whole requires simulations on cosmic scales. An international team of astrophysicists, with a ...

Since the early 20th century, scientists have gathered compelling evidence that the universe is expanding at an accelerating rate. This acceleration is attributed to what is known as dark energy—a ...

Researchers using new simulations suggest that the Milky Way’s past collisions may have reshaped its dark matter core. This distorted structure could naturally explain the puzzling gamma-ray glow long ...

Several theories have attempted to explain excess far-ultraviolet light present in the Milky Way, but none have been ...

Giant worlds beyond the Solar System could be the probe we need to figure out how dark matter manifests in the Universe. According to a new study, one particular dark matter model could see the ...

Faint radio signals from the early Universe, soon detectable by Moon missions, may reveal how dark matter shaped gas cooling and clumping in the cosmic Dark Ages. Ordinary matter, which makes up the ...

An international research collaboration has used advanced computer simulations to investigate how faint radio signals from the early universe, soon to be observed from missions on the far side of the ...
