Map of the line emission of hydrogen and oxygen in the PJ308-21 system

Caption

Map of the line emission of 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 colours of the quasar's host galaxy and companion galaxies in this map reveal the physical properties of the gas within them.
