Study reveals high-density companion galaxies around early-Universe quasar VIK J2348-3054, suggesting intense quasar radiation may inhibit nearby star formation.

A study led by Trystan Lambert using the Dark Energy Camera has revealed new insights into the environments of early-Universe quasars. It found that quasar VIK J2348-3054 is surrounded by a high density of companion galaxies, though none exist within 15 million light-years. This may clarify previous conflicting observations, suggesting intense quasar radiation could inhibit star formation in nearby galaxies. Future research aims to confirm these effects and expand understanding of quasar environments.
