An international team of astronomers has observed an extremely radio-loud quasar known as J1601+3102. As a result, they found that the quasar hosts a large extended radio jet. The discovery is reported in a research paper published Nov. 25 on the arXiv preprint server.
Quasars, or quasi-stellar objects (QSOs), are active galactic nuclei (AGN) of very high luminosity powered by supermassive black holes (SMBHs), emitting electromagnetic radiation observable in radio, infrared, visible, ultraviolet and X-ray wavelengths. They are among the brightest and most distant objects in the known universe, and serve as fundamental tools for numerous studies in astrophysics as well as cosmology.
J1601+3102 is an extremely radio-loud quasar at a redshift of 4.9, discovered in 2022. It has a radio flux at a level of 69 mJy, bolometric luminosity of about 26 quattuordecillion erg/s and a steep spectral index.
