What to know about Dormant black hole revives in under three years, brightening 10-fold in nearby galaxy

Astronomers used the Neil Gehrels Swift Observatory to monitor the Seyfert galaxy ESO 511-G030, observing a supermassive black hole's accretion disk revive and brighten significantly between 2021 and 2023. The study suggests that the physics governing accretion-state transitions in supermassive black holes may be similar to those in stellar-mass black holes, although the observed timescales challenge standard theoretical models.

Common ground

Feeding habits In active galactic nuclei (AGN), material spiraling into the central black hole releases enormous amounts of energy.
