Astronomers discovered the largest radio jet ever, emitted by a quasar from when the universe was 1.2 billion years old, stretching 200,000 light-years, and powered by a modest black hole, revealing new insights into early galaxy evolution.
Astronomers have discovered a large extended radio jet in the quasar J1601+3102, located at a redshift of 4.9. Using the Low Frequency Array (LOFAR) and Gemini Near-Infrared Spectrograph (GNIRS), they found the jet spans at least 215,000 light years, making it the most extended radio jet observed at such a high redshift. The quasar's supermassive black hole is about 450 million solar masses, suggesting that exceptionally massive black holes are not necessary to produce powerful jets.
Astronomers using the upgraded Giant Metrewave Radio Telescope (uGMRT) have detected a large-scale bent radio jet in the galaxy cluster Abell 514. The radio emissions originate from the active galactic nucleus (AGN) and extend towards the southern periphery, with a measured size of about 2.3 million light years. The observations also revealed a discontinuity in X-ray surface brightness and high polarization, indicating jet plasma redistribution along the cold front of a recent cluster merger. This finding contributes to our understanding of large-scale structure formation and the evolution of the universe.
