Black holes may spit out nearly as much matter as they swallow
Astronomers have observed a black hole system, Swift J1727.8 1613, that expels significant amounts of matter through jets and winds rather than consuming everything. This suggests that black holes function more like complex digestive systems than simple gravitational pits.
Why it matters
This discovery challenges long-held assumptions about black hole feeding processes and provides new insights into high-energy cosmic phenomena.
Astronomers led by the University of Warwick have uncovered what they describe as a kind of cosmic digestive system around a black hole. Their observations show that even when a black hole appears faint, it may still be actively expelling large amounts of matter rather than simply swallowing everything nearby.
Black holes are often pictured as unstoppable cosmic gluttons. However, new observations of a dramatic outburst led by Warwick Postdoctoral Fellow Dr. Noel Castro Segura reveal a far more complicated feeding process.
Using the European Southern Observatory's Very Large Telescope (VLT), the team tracked the recently discovered black hole system Swift J1727.8 1613 throughout a spectacular eruption in 2023.
