In the 1930s, Swiss astronomer Fritz Zwicky observed that the velocities of galaxies in the Coma Cluster were too high to be maintained solely by the gravitational pull of luminous matter. He proposed the existence of some ...

A new study in Physical Review Letters offers the first detection of the cross-correlation between cosmic shear and diffuse X-ray background, helping to understand the distribution of baryonic matter in the universe.
One of the big mysteries about dark matter particles is whether they interact with each other. We still don't know the exact nature of what dark matter is. Some models argue that dark matter only interacts gravitationally, ...

The team of physicists working on the LHCb Collaboration at CERN has found that bottom quarks are more likely to exist in baryons than mesons as the density of the environment in which they exist increases. In their paper ...
Researchers at the University of Kansas (KU) hope to better understand intricate mechanisms behind the evolution of galaxies, which travel through a "cosmic web" of different environments during their lifespans.
