Supermassive black holes are, as you might imagine, quite large, millions or even billions of times larger than the Sun. They lurk at the centers of all large galaxies, including our Milky Way, and shape the growth of these cosmic structures. But little can be said with certainty about how they form and why they grow so large.
These mysteries have been brought into sharper focus in recent years thanks to the James Webb Space Telescope (JWST). JWST traveled deep into time to discover an astonishingly large number of supermassive black holes in the early universe. Interestingly, just a few hundred million years after the Big Bang gave birth to our universe, the universe already contained black holes that were too massive to be understood by current models of how the universe evolved. It seems that it was. There just wasn’t enough time for something this huge to form.
Sophie KudmaniAstrophysicists at the University of Cambridge are among those trying to solve this challenge. She uses supercomputer simulations to model galaxies and supermassive black holes in the early universe, testing ideas about their origin and growth, and even predicting what to look for in future observations. .
Mr Koudmani said: new scientist Why supermassive black holes are so fascinating, the joy of discovering surprises that raise new questions in the early universe, and…
