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 ...
