AI Unveils Rapid Spin and Secrets of Black Holes

Scientists have discovered that the supermassive black hole at the center of galaxy M87 is spinning at 80% of the maximum possible speed, making it the fastest spinning black hole ever observed. Using Event Horizon Telescope imagery and relativistic physics, they measured its rapid rotation and the rate at which it consumes matter, which is about 23% of the speed of light. The black hole's intense activity powers a massive jet of plasma, influencing its galaxy's evolution.

Unveiling the Secrets of M87's Jet and Black Hole Spin

Astronomers have discovered an unexpected alignment between the jet and novae in the nearby galaxy M87. Using data from the Hubble Space Telescope, researchers found that novae occur more frequently along the path of the galactic jet. The cause of this phenomenon is still unknown, with theories ranging from radiation heating donor stars to shock waves shepherding gas and dust to trigger novae. Further research is needed to unravel this mystery and determine if this connection is unique to M87 or a common occurrence in galaxies with jets.

Unveiling Galactic Black Holes: Mysterious QPO Signals Expose New Features

An international team of scientists has detected a quasi-periodic oscillation (QPO) signal in the radio band from a Galactic black hole system, specifically the microquasar GRS 1915+105. This is the first time such a signal has been observed in microquasar systems, and it could provide evidence of a "jet" launched by a Galactic stellar-mass black hole. The QPO signal has a rough period of 0.2 seconds and appears under special physical conditions. Further observations are needed to fully understand these intriguing signals and their implications for black hole behavior.
