Dark matter halos are everywhere in the universe, yet no telescope can see them. These vast, invisible structures surround ...

Galaxy clusters are the largest gravitationally bound structures in the universe, with each containing hundreds or even thousands of galaxies. When two of these giants collide, they send powerful ...

Cosmological accretion shocks created during the formation of galaxy clusters are a ubiquitous phenomenon all around the universe. These shocks and their features are intimately related with the ...

Galaxy clusters are the most massive objects in the universe held together by gravity, containing up to several thousand individual galaxies and huge reservoirs of superheated, X-ray-emitting gas. The ...

Astronomers have explained how a galaxy cluster maintains its heat, despite emitting X-rays that cool the hot gas at its center. The group discovered the existence of a fast-moving, high-temperature ...

Galaxies rarely live alone. Instead, dozens to thousands are drawn together by gravity, forming vast clusters that are the largest objects in the universe. “Galaxy clusters are one of the most ...

Artist’s impression of the center of the Centaurus Cluster. Blue shows a vast flow of hot gas, white shows galaxies, and reddish brown shows cool gas. Tokyo, Japan – The XRISM collaboration have ...

A team of astronomers used the Hubble Space Telescope to find the best evidence yet for the existence of dark matter, present in the form of a ghostly ring in a galaxy cluster. The ring had formed ...

The XRISM science team, including members of Nagoya University, has explained how galaxy clusters maintain their heat despite emitting X-rays, which typically have a cooling effect on the hot gas. By ...
