Briefings

Astronomers identified two active supermassive black holes in galaxy MG B2016+112, located 175 parsecs (570 light-years) apart, at a redshift of 3.273 corresponding to an early universe epoch 2 billion years after the Big Bang. This system, the most compact dual active galactic nuclei (AGN) known at this redshift, was discovered via a preprint posted to arXiv on September 25, 2026.

Key points

• Two supermassive black holes are actively feeding each other in galaxy MG B2016+112, separated by 175 parsecs (570 light-years) at a redshift of 3.273.
• The system represents the most compact dual AGN known at redshift 3.273, with both black holes currently in an active state.

Context and limitations

The study is a preprint posted to arXiv on September 25, 2026, and the specific observational data and confirmation status are not fully detailed in the provided evidence.
