Preprint identifies powerful radio galaxy from the early universe

Astronomers measured radio galaxy TXS 2354+015 at redshift 4.946, when the universe was under 1.2 billion years old, Phys.org reports. Researchers say its radio power exceeds known high-redshift comparisons. The September 23 arXiv preprint has not been peer reviewed; estimates of its host galaxy’s mass carry large uncertainties.
