An international team of researchers has found evidence of a ridge of radio emissions joining two galaxy clusters. In their paper published in the journal Science, the group describes their find and how it fits into cosmological ...
Astronomers have found evidence for a faded electron cloud "coming back to life," much like the mythical phoenix, after two galaxy clusters collided. This "radio phoenix," so-called because the high-energy electrons radiate ...

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 ...
An international team of scientists has pushed the limits of radio astronomy to detect a faint signal emitted by hydrogen gas in a galaxy more than five billion light years away—almost double the previous record.
