For the first time, physicists have captured direct images of 'second sound,' the movement of heat sloshing back and forth within a superfluid. The results will expand scientists' understanding of ...

ESA’s XMM-Newton X-ray observatory has spied hot gas sloshing around within a galaxy cluster – a never-before-seen behaviour that may be driven by turbulent merger events. Galaxy clusters are the ...

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 ...

Almost all galaxy clusters experience mergers. While a merger takes place, a specific pattern of “spiral” often can be observed in X-ray images. Such a spiral feature is due to the motion of the gas ...

The 'sloshing' of a quantum fluid comprised of light and matter reveals superfluid properties. An Australian-led team of physicists have successfully created sloshing quantum liquids in a 'bucket' ...
