Summary

Story summary

Astronomers found an off-center active galactic nucleus (AGN) in a dwarf galaxy 230 million light years away, challenging existing black hole theories.
The black hole is 3,200 light years from its galaxy's center and actively accretes material, generating AGN jets.
This discovery indicates black holes can grow outside galactic centers, where gas is usually plentiful.
Led by Yuanqi Liu, the research is part of the MaNGA survey, identifying 628 dwarf galaxies with candidate AGN.
Approximately 62% of these AGN may be offset from their galactic centers, suggesting new pathways for black hole growth.
