The James Webb Space Telescope captures a staggering quasar-galaxy merger in the remote universe - EurekAlert
Rome, 05 July 2024 – An international research group led by the Italian National Institute for Astrophysics (INAF) and comprising 34 research institutes and universities worldwide utilised the Near-Infrared Spectrograph (NIRSpec) on board the James Webb Space Telescope (JWST) to witness the dramatic interaction between a quasar inside the PJ308–21 system and two massive satellite galaxies in the distant universe. The observations, made in September 2022, unveiled unprecedented and awe-inspiring details, providing new insights into the growth of galaxies in the early universe. The results, presented today during the 2024 European Astronomical Society (EAS) meeting in Padua (Italy), will be published soon in Astronomy & Astrophysics.
