Astronomers have discovered the second-strongest merger shock in clusters of galaxies ever observed.
Using a computer simulation, astronomers probe the ‘cosmic web’ of the universe, its honeycomb-like structure on the largest scales.
Galaxy clusters are groupings of hundreds to thousands of galaxies bound together by gravity, and are the most massive structures found in the universe.
A new theory suggests a shorter secondary inflationary period that could account for the amount of dark matter estimated to exist throughout the cosmos.
There's a new player in the hunt for dark matter: China's Dark Matter Particle Explore (DAMPE) satellite, which launched on December 17. Ground stations have just received the first data beamed back from DAMPE. With all systems fully operational, the satellite officially begins its three-year mission.
The physicist predicts densities of up to 1 billion times greater than normal.
A new machine-learning simulation system promises cosmologists an expanded suite of galaxy models -- a necessary first step to developing more accurate and relevant insights into the formation of the universe.
