"Galaxy clusters are also dominated by dark matter," Jacqueline McCleary, assistant professor of physics at Northeastern University, said in a statement. "Eighty to 90% of their mass is dark ...

Hubble's new image of galaxy cluster Abell 209 reveals over 100 galaxies and gravitational lensing effects from dark matter ...

Galaxy clusters, which consist of thousands of galaxies, are important for exploring dark matter because they reside in a region where such matter is much denser than average.

Map of galaxy clusters Abell 222 and 223, with a filiment of dark matter connecting them. The contours and the blue color represent the distribution of mass, as determined by weak lensing.

Galaxy clusters, which consist of thousands of galaxies, are important for exploring dark matter because they reside in a region where such matter is much denser than average.

Observations of 11 galaxy clusters, such as MACSJ1206.2-0847 (shown), reveal that some globs of dark matter in these clusters are denser than expected.

Using data from the Hubble and Chandra space telescopes, scientists have determined that dark matter ghosted through the wreckage of two colliding galaxy clusters over 5 billion light-years away.

Dark matter and galaxy clusters Although it accounts for 90% of all matter in the universe and more than a quarter of its energy, we know very little about dark matter.

Moreover, when galaxy clusters collide, mass reconstruction from weak lensing shows an inescapable separation from normal matter. No alternative gravity theory explains all this. We need dark matter.

An international team of researchers claim that the internal structure of vast galaxy clusters, containing thousands of individual galaxies, may be shaped by the dark matter environments in which ...

Particle accelerators like the Large Hadron Collider have failed to turn up potential dark matter candidates, but could galaxy cluster smashes be used as cosmic dark matter colliders?
