The researchers found a huge clump of dark matter about 1.4 million light-years west of the cluster’s center.

"All the odd shapes and swirling gas observed in the Perseus cluster now make sense within the context of a major merger." Dark matter is the invisible substance believed to account for around 80 ...

Astronomers have discovered a rare kind of galaxy that seems to be missing one of the universe’s most important ingredients: ...

"Globular clusters are often used as a proxy to estimate ... may have separated the galaxy's dark and visible matter, a formation scenario known as 'the bullet-dwarf model." However, additional data ...

T he Perseus cluster is enormous. It has a mass equivalent to 600 trillion Suns, and it looks like it has not stopped growing ...

These measurements revealed a slow speed among the clusters, a key indicator that the galaxy lacks the strong gravitational pull expected from dark matter, the new study reports. No known scenario ...

An international team of astronomers has solved one of the longstanding cosmic mysteries by uncovering direct evidence of a ...

Moreover, the team found that this newly identified structure appears to be connected to the Perseus cluster's core by a faint "dark matter bridge"—providing direct evidence of the pair's past ...

the central galaxy of the Perseus cluster. These two elements seem to be connected by a faint "bridge" of material. The structural backbone of this bridge is dark matter, the universe's most ...

This clump is linked to the core of the Perseus cluster by a much lighter but significant dark matter bridge. The team performed simulations of the Perseus cluster, which revealed that this clump ...
