For the First Time Astronomers Watch a Black Hole ‘Wake Up’ in Real-Time
In a groundbreaking event, astronomers have witnessed a black hole “waking up” for the first time, as recorded by Lorena Hernández-García of Valparaiso University in Chile. The phenomenon observed involves a black hole named Ansky emitting X-ray bursts that defy existing theories about black hole lifecycles. These bursts are significantly more powerful than previously recorded eruptions, highlighting new avenues for understanding these cosmic giants.
Key Points
- This is the first time researchers have observed a black hole “waking up” in real-time.
- The black hole Ansky emitted X-ray bursts ten times longer and brighter than typical eruptions.
- These bursts release a hundred times more energy than previously recorded QPEs (quasiperiodic eruptions).
- The observed cadence of 4.5 days between eruptions is unprecedented.
- New theories are being considered about the origins of the accretion disc related to Ansky’s behaviour.
