Briefings

Astronomers announced the detection of a supermassive black hole-powered blazar at a distance of 13.4 billion light-years, representing the most distant such object ever observed. This event occurred approximately 13.4 billion years ago, coinciding with the early universe's formation. The source is a blazar named 13C 349, which emits high-energy radiation from a black hole accretion disk. The discovery challenges previous models of black hole growth in the early universe, suggesting rapid accretion rates were possible. The event is significant for understanding cosmic evolution and the mechanisms of high-energy astrophysics in the early cosmos.

Key points

• Astronomers detected a supermassive black hole-powered blazar at a distance of 13.4 billion light-years, identified as 13C 349.
• The event occurred approximately 13.4 billion years ago, marking the early universe's formation period.

Context

This discovery is significant for understanding cosmic evolution and the mechanisms of high-energy astrophysics in the early universe, challenging previous models of black hole growth.

Limitations

The evidence is a single observational event from a preprint submission on r/space, with no additional observational data or follow-up measurements provided. The exact nature of the black hole's accretion rate remains uncertain without further analysis of the spectral data.
