When a black hole refuses to play by the rules 🕳️ Our XMM-Newton has uncovered something truly extraordinary at the heart of a nearby galaxy: a supermassive black hole behaving in ways that challenge everything we thought we knew about these cosmic giants. Here’s the story: - Meet 1ES 1927+654, a supermassive black hole that’s been under XMM-Newton’s watchful eye since 2011. While it behaved as expected at first, things took a wild turn in 2018 when an outburst caused its X-ray corona to vanish — only to reappear later. - Fast-forward to July 2022, when the black hole’s X-rays started fluctuating rapidly. These mysterious signals, known as quasi-periodic oscillations, are rarely seen in supermassive black holes. What’s causing the oscillations? Astronomers believe a white dwarf — the remnants of a dead star — is caught in the black hole’s accretion disc, orbiting at incredible speeds. Calculations suggest it completes an orbit every 7–18 minutes, travelling at up to half the speed ...
