An international team of astronomers has performed radio observations of a massive galaxy cluster known as ACT-CL J0329.2-2330, which resulted in the detection of a new radio halo in this cluster. The finding was reported ...
A new record for the most distant galaxy cluster has been set using NASA's Chandra X-ray Observatory and other telescopes. This galaxy cluster may have been caught right after birth, a brief, but important stage of evolution ...
