Star formation has ceased within at least 16 million light-years of the quasar. A similar phenomenon may have fried the Milky Way when it was young.

The quasar imaged by the team in X-rays is known as SMSS J114447.77–430859.3 (J1144) and is the most luminous example of such an object seen in the last 9 billion years of cosmic history.
