Le secret caché des plus gros trous noirs de l'univers ! (trous noirs supermassifs)

Black holes are fascinating, but some are beyond imagination. Millions, sometimes billions, of times the mass of the Sun. They are called supermassive or even hypermassive, and they lurk at the heart of galaxies. Including our own. But where do they come from? How can they grow so fast, so early in the history of the universe? And why do some seem completely invisible when they should shine like a thousand suns? Recently, astronomers spotted something strange near the galaxy M83: an emission of highly ionized neon, detected using the James Webb Space Telescope. A rare, extremely energetic signal... and one that could well betray the presence of a hidden, previously undetected giant black hole. We delve into this mystery: what we know today about supermassive black holes, the largest ever discovered, like TON 618, the hypotheses about their formation (accretion, direct collapse, cluster mergers), and the methods for tracking them billions of light-years away. And then there's the question everyone's asking: how many of them still elude us? Hidden in the dust, silent, but definitely there...
