An international research team, led by the Italian National Astrophysical Institute (INAF), has used the James Webb Space Telescope (JWST) to capture an extraordinary event in the distant Universe: the dramatic interaction between a quasar and two massive satellite galaxies in the PJ308-21 system. This remarkable discovery provides new insights into the growth of galaxies … Read more
Map of the line emission from hydrogen (in red and blue) and oxygen (in green) in the PJ308-21 system, shown after masking the light from the central quasar (“QSO”). The different colors of the quasar’s host galaxy and companion galaxies in this map reveal the physical properties of the gas within it. Credit: Decarli/INAF/A&A 2024 … Read more
