Quasar J1601+3102

Using a combination of telescopes, astronomers have discovered the largest radio jet ever found in the early Universe. The jet was first identified using the international Low Frequency Array (LOFAR) Telescope, a network of radio telescopes throughout Europe. Follow-up observations in the near-infrared with the Gemini Near-Infrared Spectrograph (GNIRS), and in the optical with the Hobby Eberly Telescope, were obtained to paint a complete picture of the radio jet and the quasar producing it. GNIRS is mounted on the Gemini North telescope, one half of the International Gemini Observatory, funded in part by the U.S. National Science Foundation and operated by NSF NOIRLab.

A portion of this image was taken as part of the DECam Legacy Survey (DECaLS), one of three public surveys that jointly imaged 14,000 square degrees of sky to provide targets for the ongoing Dark Energy Spectroscopic Instrument (DESI) Survey. DECals was conducted using the 570-megapixel Department of Energy-fabricated Dark Energy Camera (DECam), mounted on the U.S. National Science Foundation Víctor M. Blanco 4-meter Telescope at Cerro Tololo Inter-American Observatory (CTIO) in Chile, a Program of NSF NOIRLab.
