Dormant black hole revives in under three years, brightening 10-fold in nearby galaxy
Astronomers observed a supermassive black hole in the galaxy ESO 511-G030 brighten tenfold over three years as it revived from a dormant state, with ultraviolet and X-ray emissions showing distinct recovery timelines. The black hole, about 17 million times the mass of the Sun, had been significantly dimmer since 2019 compared to observations from 2007 and 2012. The study, using data from the Neil Gehrels Swift Observatory, provides new insights into how black holes and their surrounding structures, like accretion disks and coronae, evolve during periods of increased activity. This observation helps scientists better understand the processes involved in the feeding and brightening of supermassive black holes in active galactic nuclei.
A supermassive black hole in a nearby galaxy suddenly became much brighter, increasing its light output ten times over in just three years.
This rapid change helps scientists understand how black holes can transition between dormant and active states, offering clues about galaxy evolution.
Observing such dramatic changes in the universe fosters curiosity and deepens our understanding of cosmic processes through careful, long-term study.
