Strange New Phenomenon Found After Black Holes Destroy Stars, No Explanation Yet

Astrophysicist Anton has discussed the intriguing phenomenon of black holes, specifically tidal disruption events (TDEs), and the recent discovery of so-called "zombie black holes." TDEs occur when a star or star-like object passes too close to a black hole, resulting in spaghettification and the creation of an accretion disk around the black hole, which emits high-energy emissions detectable from far away. The new mystery in this field is the "zombie black hole" phenomenon, where black holes seem to re-awaken and exhibit activity long after an initial TDE, including radioactivity bursts. This could be caused by the instability of the accretion disk over time, which can break apart and release material into the surroundings, causing powerful radio wave emissions. These "zombie black holes" could provide insights into the formation of jets around black holes, another puzzling aspect of astrophysics that plays a significant role in the evolution of galaxies. Despite some hypotheses, there is much we still don't understand about these phenomena, and ongoing research is needed to continue to unravel these celestial mysteries.
